Massive stuttering problem

[Sklav]

Hello guys, yesterday I bought the game and for the first hour I didn’t have any feedback on my DD Pro 8Nm. Fixed that, game looked great and when I got into a race with other cars I got some massive stuttering and FPS drops. I play on a Dell G15 5520 (i7 12700H / RTX 3060 / 16 GB RAM) and at first I thought high graphics was the problem. I set it to medium and turned reflections and shadows to low and now it is even worse. Came out of the pits and almost broke my fingers with the wheel, and it literally took me about a minute to exit the pits with all the stuttering. Anyone having this problem? Any fixes? Thanks in advance.

Hey - I also had really bad stuttering, even after turning settings down to low/medium etc, and was starting to worry I couldn't run the game. However, after I changed 'Post effects' to 'Low' its run like a dream, and I have had no issues. Hope that helps you, if you haven't tried that yet...

Unfortunately that didn’t work, might have to check into the game files for some solution, the visible cars is also set to 20 so that isn’t the problem either

Yes, I think the framerate wouldn't be too bad if it didn't freeze continously every few frames. I don't know what's the bottleneck... if that's RAM, VRAM, my CPU or the GPU, but I don't think that's the GPU honestly... since I'm exactly inside the "reccomended" values, my CPU is kinda old but it's an i7, it should be able to keep up. They surely need to investigate these continuous stutters.

Honestly, it is tied to the game engine at this point. I tried everything on my end.

• Turning off external app / using crewchief+tinypedal: same stutter.
  
• Using VSYNC, turning on memory usage for replay, set maximum frame at +1, changing graphical quality: same stutter.
  
• Full screen, borderless, windowed: same stutter.
  
• Changing FPS in-game / limiting FPS in Nvidia control panel: same stutter.
  
• Using HDD / using SSD: same stutter.

In all my testing the frame rate was never truly impacted, processor never went above 60% usage, graphic card stayed within expected load (depending the frame limit I set). Like any stutter issue, the frame rate would stay stable for a good amount of time and suddenly a couple of frame would be dropped with no apparent reasons.

There is most likely something in the engine/simulation causing it that cannot be fixed on the end-user side (I saw a speculation that any car bottoming out and generating sparks would be causing that stutter at the moment).

Dan Suzuki said turning off recording replays helps. I just did it and had a race without any.
worth a try, also check the official discord for tips.

I solved my problem but it's not what I want. Same stuttering issue while I'm capped at 75fps with my gpu usage at 45%, even the power draw of the graphic card is at half its max (HWmonitor).
I tried every tips, modifying the setting .json ... different vsync, turned off replay, everything ... the only thing that solved my problem is turning off the Vsync, I'm at 260Fps and no stuttering.
i7 13700K, 32Gb DDR5, RTX 3080Ti

It's a classic actually, I remember many racing game with this issue. Even ACC has it in some ways. In ACC tho there is an option to set a cap for the FPS, so I turn off the Vsync set the FPS at like 90 and it's butter smooth, no tearing, not destroying my graphic card.
I'm not a dev but maybe it could be an easy fix.

In the patch note it only says
"Hotfix #5

Fixed the “teleport” bug for online users that had pressed “esc” on their previous race, resulting in the user being magically transported to their pit-box after the leader crossed the line in the following race and causing a DNF
"

I had similar problems even lowering details didnt help if not made it worse.

Try borderless window mode with software vsync or video vysync on.
For me software vsync solved my problems. video vsync caused the problems for me. but i heard for some ppl its the other way around.
Dont turn vsync off, it will make the menus stutter.

Rumour has it that a big patch is coming this week at some point.

If you're running 16Gb RAM, then that's not enough for the bigger tracks. Test it with Task manager (second tab), when you're running the Le Mans track with a full grid. All the cars get simulated, regardless of graphic settings. That's what caused all my stuttering, I fixed it with RAM without adjusting my graphics.

It uses rf2 engine you need a bloody great CPU and a good GPU 32 gig min 16 not enough rf2 users will tell you that.
