Project CARS Visual Analysis: PC vs. PS4 vs. Xbox One

Slightly Mad Studios’ long-awaited racing simulator comes loaded with options.

Posted By | On 05th, Jun. 2015 Under Article, Graphics Analysis

You’ve heard it all before. “So-and-so’s racer is perhaps one of the most anticipated racing titles of all time”. It’s hard to resort to that classic hyperbole anymore though. After all, Forza Motorsport is now a yearly franchise, Gran Turismo isn’t completely relegated to the ether and iterations to DIRT, F1 and Need for Speed are fairly regular. However, there are also games like Slightly Mad Studios’ Project CARS. Though it didn’t have the biggest financial backing or the smoothest development process – the game was delayed multiple times over the past year alone – Project CARS stands as a testament to modern day racing game visuals. It’s one of those games which shines on PC but also proves the Xbox One and PS4 aren’t slouches either.

Let’s get into the current gen console versions first. The PS4 and Xbox One iterations both run at an unlocked 60 FPS per second with the former running at native 1920×1080 resolution and the latter at 1600×900 resolution. Both use a rather interesting form of multisample anti-aliasing or MSAA. This is actually EQAA (Enhanced Quality Anti-aliasing), developed by AMD and consisting of four samples with eight fragments. It’s meant to resemble MSAA 4x on the PC and it’s a step up from FXAA. Oddly enough, the PS4 version’s temporal anti-aliasing results in ghosting during some moments.

Right off the bat we were impressed with the level of detail in both versions. Motion blur is apparent in both versions, running at the equivalent of the PC’s medium settings, and 8x anisotropic filtering is apparent as well. This leads to some fairly good texture quality and sharpness, especially on the tracks themselves. Most of the graphical settings are hard-coded to the PC’s equivalent of medium settings with some bordering on medium to  high.

Frame rate performance is more or less as you’d expect on both consoles. Slightly Mad Studios was targeting to run Project CARS 60 FPS on current gen hardware and although it falls shorts it does try very hard. When playing the career mode, you’ll notice a fairly good frame rate between 50 to 60 FPS. The PS4 version is capable of maintaining 60 FPS more consistently thanks to its superior GPU and while the Xbox One tries to stick to it resulting into some screen tearing.

When the real-time weather really starts kicking in is when the frame rate takes a dive. It went close to 50 FPS on the PS4 while the Xbox One managed to hang in the upper 40s. The engine is further stressed as more cars fill up your screen and the screen tearing becomes more prominent in such cases. It’s nice to have so many PC-like options on both console versions though and we especially appreciated the post-processing effects although its t impact on performance is debatable

On the PS4, it’s interesting to see the shadow detail vary between medium PC settings, relying on 1024×4096 shadow settings with 32 bit precision whereas the same setting on PC uses 16 bit precision. Track detail and quality equal the PC version’s high setting and even the car detail is in the high range. LOD scaling for car shadows usually ranges from medium to high.

As for the Xbox One version, that seventh CPU core is in effect. Well, at least 50 percent of it is. This is used for miscellaneous tasks such as engine sound synthesis, grass generation and audio mixing. It certainly helps to keep the Xbox One version running smoothly and hopefully, future patches will utilize more of the seventh core’s power.

Despite 8x anisotropic filtering on both consoles, texture filtering in the PS4 version is lower quality compared to Xbox One but it must be noted that this deficiency is not present everywhere While track details are fairly similar across all consoles, the foliage density for tracks on PS4 and Xbox One are comparably medium to the PC version. Car reflections on both consoles also used the medium environmental map quality from the PC version. Environmental reflections on steering wheel seems to be crisper on the PS4 compared to the Xbox One. Compared to the PC version, light reflections on the wet ground is almost absent when in motion on the consoles.

Comparing polygon counts, the console versions feature 60,000 polygons per car, which is the same as the high setting on PC. The PC version can go beyond this though with the ultra setting offering 200,000 to 300,000 polygons per car. The shadows used in Project CARS are intriguing as cars, tracks and track side objects are rendered into cascaded shadow maps. This single cascaded map takes the entire world’s geometry and bakes opaque shadows using a light pre-pass keylight. Windshields and water droplets thus have their own shadows and even stray particles can emit shadows on consoles. The effect is a little odd on particles since smoke and dust use a standard quad-based approach and while shadows help integrate them into all lighting conditions, their quad-based nature can be highlighted at times.

Here’s a further breakdown of the game’s cascaded shadow map settings. These details were revealed by the developer on Neogaf:

  • PC Low – 512×2048, 16bit, 2 spot shadows
  • PC Medium – 1024×4096, 16bit, 2 spot shadows
  • PC High – 1408×5632, 32bit, 4 spot shadows
  • PC Ultra – 2048×8192, 32bit, 4 spot shadows + enables shadows in Environment Maps
  • Console -1024×4096, 32bit, 4 spot shadows

Screen space reflections aren’t seen in Project CARS. Rather, reflections use a six directional render from a point below the track, resulting in a cube map. Though it can be more expensive, it produces a finer quality result and avoids the limitations of screen space reflections. Car models on both consoles and PC use four LODs: LODA 60k triangles, LODB 25/26k, LODC 4K and LODD 0.8k. The PC version uses an extra LOD for the player car on ultra Vehicle Detail settings, enabling LODX models with 200,000 to 300,000 triangles.

A light pre-pass renderer can also be observed in Project CARS, resulting in two EQAA resolves. When switching off motion blur on PC, each sample of the MSAA target is tone-mapped individually. Consoles, incidentally, always have motion blur enabled resulting in per sample tone-mapping switched off.

Testing PC frame rate performance, we took an Intel Core i7-5960X with 16 GB of memory and ran the game at Ultra settings across a variety of GPUs.

  • Nvidia Titan X: 69 frames per second
  • Geforce GTX 980: 68 frames per second
  • Radeon R9 290X: 51 frames per second
  • Radeon R9 290: 45 frames per second
  • Geforce GTX 960: 55 frames per second
  • Geforce GTX 770: 46 frames per second

If it hasn’t been made clear enough already, we recommend the PC version of the game. There’s an unprecedented amount of visual detail here with plenty of customization options. It’s also to Slightly Mad Studios’ credit for featuring such a large number of cars on track along with such a hefty career mode.

Due to their general reliance on medium to high settings and frame rate quibbles during heavy weather, the console versions are recommended second. We actually preferred the PS4 version over the Xbox One due to its higher consistent frame rate and native 1080p resolution, though both versions look phenomenal when you consider the translation required from PC to console.

    Consoles are you even trying?

      I’m only speaking as an xbox user, I didn’t want 1080p as 900p gives a great game.In fact you’ll see more xbox users supporting and wanting 720-900p.
      But the main thing – gaming is about the games anyway.
      You PC types keep playing 3dmark to get those extra points and plug those water cooling leaks.

      Console peasant with a gimmick copying some other console peasant

      Kinda like yearly COD Rehashes :^)

      Enjoy your 30FPS Downgradestation 4, console peasant b*tthurt enough to copy the gimmick of another console peasant :^)

      Well struck. bro, you don’t have say here…PC is superior to consoles….although you need lots of money to get that level of superiority…the equivalent PC required to play PCars at the level PS4 does, with cost probably twice that of a ps4….so its diff strokes for diff folks i guess

    • Psionicinversion

      no it doesnt actually, be maybe $400-500. If you bought a system for $800 it would blow the back doors off the PS4 you console guys think you need a really expensive PC to match the PS4 but you really dont and we are running a crappy old slow API DX11. Under DX12 we will get big improvements for nothing.

      Under Windows 10 DX11 games get a boost at least of PC AMD GPU’s because its the first driver release that is multi threaded that can easily add 5-10 fps on its own. Maybe a little less for nvidia cus there drivers are better

      Also win 10 manages resources far more efficiently everything is properly multithreaded adding speed and generally its going to be an awesome OS…. for PC. Shoudl fix the clunkiness of xbox OS as well and more importantly unify the MS platform

    • Phillip de Villiers

      i am actually stupefied as to why on earth they actually compare PS4 and xbox One to PC. PC is always going to be far better. as a PS4 owner i am happy with PS4….the only time one can compare it, is when said PC is on par with hardware of that of the PS4 and xbox one. PC fanboys always revert to this type of BS, when the reality is, you can’t compare the two. however, when you compare PS4 to Xbox One. thats alright…sorry to xbox one users but Microsoft screwed that machine up for you. i come from xbox, and i loved my 360, i am still jealous of forza, and the xbox one for the console, it’s crap.

      How did they screw up the XBOX One machine?
      We got the TV focused machine we always asked for and still the only console that can snap in live tv and sales of the Kinect blow the doors of the Sony eye, showing people selected Kinect along with their Xbox. The first 3 months the attachments rate was 100%, that’s how much people supported it.

    • Phillip de Villiers

      Really? a TV focused machine? tell me again what the point of a gaming console is, take into account the operative word “gaming”…the games that are really benefit from kinect are very childish kinda like WII….you are seemingly veering off the actual xbox to its peripherals. when project morpheus comes later this year. your kinect will make xbox fall into category WII. PC with Oculus Rift. we talking gaming here…not kinect or sony eye..if you can understand that, then youll understand why microsoft screwed up xbox…and what your 900P downscale still didn’t bring much more performance…actually none…imagine xbox running 1080p…it would struggle 60fps as it does already. if you read the review above ps4 has the advantage over the xbox in nearly every aspect, that goes for all games that they both have…and PC rapes both respectively. now tell me how many customers would opt for the xbox if you told them that? that’s excluding moms with little children wanting to stand up on a raft and go down rapids with kinect….gamers want a gaming console…not a tv HUB…those factors are just irrelevant…as we talking of gaming capabilities here.

      they compare it to see the visual differences between console settings and max. also its good to see what type of PC is needed to match the console settings. at a playable framerates.

    • DiFiasco

      except the PS4 only cost $400. PC Master Baters indeed.

    • You Are Flat Out Wrong

      For a bad version of the game. Meanwhile a $400 PC Runs it better with an i3/750Ti combo.

      Stay cucked, peasants

    • DiFiasco

      Nice try

  • XbotMK1

    So the PS4 wins again. The PS4 version was obviously going to be better than the Xbox One version and we all know PC is irrelevant. PC is for peasants who play graphically inferior games like Counter Strike and League of Legends all day in their mother’s basement.

    • Psionicinversion

      actually PC wins mate, that i3/750Ti still spanking your @$$ eh hahaha wait for the DX12 patch it will blow the PS framerate to dust

    • Terminator

      LOL! Delusional Sony Pony D*ck Rider at his best! My god you are brain dead XbotMK1

    • You Are Flat Out Wrong

      Delusional as usual, John Derp

      PC wins again and again and again :^)

    • XbotMK1

      PC allways loses which is why nobody plays on it besides a few who only play DOTA and League of Legends all day. LOL ;^)

    • You Are Flat Out Wrong

      PC has better graphics than PS4. What does that say about how garbage the PS4 is?

    • XbotMK1

      Nice bullshots LOL. It’s not worth the money just for minimal improvements over the console version. Nobody has a PC strong enough to run The Witcher 3 at max settings which is why PC is only played by jobless bums who only play old games like League of Legends and DOTA. ;^)

    • You Are Flat Out Wrong

      Bullshots only exist on consoles and for weak sauce graphical games like DriveDud. PC Gaming gets you the real deal and massive improvements. PC Gaming gets you mods. PC gaming gets you no framedrops like the POS4 version.

      And the fact people still play those games show PC has better games and backwards compatability. No garbage like the Odor 800P or DriveDud loser :^)
