pc stuttering issues

[gibo122]

Hi all

I have it running on my pc capd at 60fps. As i have seriously bad stuttering, to the point were the ai cars stutter back and forth its really bad, it seems to happen mainly wen im turning into corners.

I have a gtx970, 4690cpu, 16gb ram i can run it fine on high settings but even on low this stuuter is really bad. Im also using a 360 controller, tried turning ffb off doesnt help. Im stumped! All my drivers are updated etc

Any help please?

Try turning off detailed grass if you haven't already and report back.

Hi gibo122, do you get the same stuttering in Free Practice, or only with other AI cars??

yea even wen im on my own this stutter is there. Its unplayable if i dont turn vsync on from my nividia controll panel

Well, fwiw, I have to use vsync or else I get stutter even at 100+ fps. However, I tend to always use vsync in my games as I hate SLI induced micro stutter. (I realise you are not using SLI but as I say, I see micro-stutter at 100+ fps without vsync, but am butter smooth 60fps with vsync).

I also cannot enable detailed grass without micro stutter.

Might be worth a shot to disconnect the Xbox controller and start the game with just the Keyboard, just to 100% eliminate any possible issue with the Xbox controller and the issues some people are seeing with FFB.

I figured out 3 issues on my PC what causing stuttering:

1.) UHD Resolution (45-60fps shown but massive microstutters)
2.) Grass on minimum leads to more stuttering than on high, high seems to work much better
3.) Shadows on Ultra or High causing massive stuttering on normal and high end PC's, for that may be you need SLI system.

I am wondering if the fps (I use the Steam Counter) are shown correctly? Fact is, 45 fps are smoother than 60 using above settings.

Good tip about the detailed grass, GAT Montana, I will have to give that a try

I think ive fixed it. so if u go into the options and go to visuals, then hardware. Theres a slider called jitter tweak. Default is 4.0 So i started playing with it. moving it higher i saw less stutter, im now at 20.0 and there nearly gone. I read it may cause input lag, but i havnt noticed any Lag at all from my contoller

Thanks for help guys
