I hope this gets optimized better for my R9 290 soon. Runs like shit right now.

Project CARS PC Performance Thread
- Thread starter Salty Hippo
- Start date
I'll start off by saying this is probably the best-looking racer I've played, those weather transitions while you're frantically jostling for position give me the goosebumps.
4670k@4.3
780@1137
16Gb
SSD
Windows 8.1
350.12
144Hz, VSync Off
Everything max or on at 1920x1080 except AA set to MSAA only and motion blur on medium. Dry weather with full grid depends on circuit, but normally between 60-90fps. Wet weather is completely different story. Thunderstorm I've seen as low as 32, but mostly settles at a very playable 40-45. There's hardly anything in the way of stutter, and the worst is at the start and first few corners where the cars are tightly grouped. I'm guessing it's all the added road and surface reflections that cause the bother. Framerate doesn't change nearly as much in the dry when lots of cars are present.
Nothing extraordinary going on in terms of VRAM, around 1.7Gb. RAM demands similarly light at 3.5ish. GPU use mostly 98%, but sometimes dropping inexplicably to the 80s despite an almost constant CPU usage of 70-80% across the 4 cores.

Nvidia users should set their grass detail from ultra to high if you're on ultra and want a nice FPS boost.
Per Rofas on the WMD forum:
I tested this myself and can confirm a solid 5~10 fps boost with heavy traffic/cars on the screen (which was the only time the frame rate dropped out of 60)
Also after testing various combinations of AA and downsampling to see what could give the cleanest lines vs best performance, it seems like running native @ 1080p with Nvidia MFAA and DS2x AA in game yields the best looking image and best frame rates.
bumping up to 1440p and lowering DS2x to "High" came close in terms of IQ but frame rate was a little lower.

Didn't think people where still posting in this thread, if anyone is interested i made a proper PC performance thread (in that it has a lot of info in the 1st post relating to a general performance thread) 2 days ago.
http://www.neogaf.com/forum/showthread.php?t=1045039
If the TC of this thread wants a full quote of mine to edit into the 1st post let me know, more than happy to have it all moved into this one.

Only just saw that you did this now but thanks for doing this.
Think I'll go with 2 980's for my upgrade.

Nah SLI scaling is pretty good in this. Check you have the SLI profile enabled.

DSOGaming talked about how the CPU was being underutilized in certain conditions
http://www.dsogaming.com/pc-performance-analyses/project-cars-pc-performance-analysis/
I took a look at my Task Manager and saw the same thing. I tested Silverstone, 32 cars, Thunderstorm and experienced the bad usage that was talked about here. Did the same test without weather and it was in the 90s.

Any AMD users try out the new drivers? Supposedly a 17% boost in performance. I think with 15.5 beta?
I hadn't played PCars enough before the driver update to really notice a difference.

Running 1440p DSR'd to 1080, lots of AA and everything on Ultra except reflections/environment map, drops to ~45fps in the absolute worst conditions (startline in heavy rain/night). Locked 60 everywhere else. Rain seems really poorly optimised to me. This is with a 980Ti.
Is there a visual comparison anywhere of the various graphics options and their impact?

On amd cpus with 4 or more cores use this cline:
-pthreads 4
I use
-novr -skipcrowds -pthreads 4
For max. performance. I got a fx8320e cpu with 280x gpu.
Here are some numbers with recent drivers :
I don't use AA at all, as I want to achieve near 60fps at all times.
I always use cockpit view and never used the HUD at all.
Particlelevel and particledensity are low.
Also oc'ing cpu was not making any extra performance a year ago in betas but now as you can see it is actually quite the opposite. I have ddr1333 ram and also making it run @ 1600 mhz made some difference. Overall from 15.4.1 to my latest numbers you can see a very nice increase :
By the way the situation with ai is a bit worse. That is my cpu's shortcoming I guess.
Even without OC 1038 dirvers are actually very good as you can see.
