Micro stutters

[Marc Collins]

Continuous, regardless of FPS. Continuous, with or without V-Sync. Started with the anti-cheat update--before that I had smooth display.

The anti-cheat update also caused a general drop in performance, but I have lowered some settings to get back to frame rates in the 60's to 90's. No issues with graphics otherwise. No major stuttering or tearing or problems...just the almost constant micro-stutters.

AMD CPU, nVIDIA GPU. Windows 10.

Any suggestions to fix this besides EA/CM suddenly becoming competent?

Try adding the game directory as an exclusion in your AV software
A clean install of your nvidia drivers might help too (use DDU to remove it completely)

I have posted a thread for intel cpu, the last update with anti cheat has improved for me the performance, and it's related only to the use of the cores, HT off, E core off has solved the issue

DDU almost always is completely unnecessary. Windows itself is capable of handling the drivers.

There are several reports of disabling e-cores on latest Intel systems helps though.

If you use V-Sync make sure you set your refresh rate to the game's 1% lows IN WINDOWS DISPLAY SETTINGS.

There are also reports for disabling control flow guard (only for this game!) in Windows exploit protection helps with UE4 stutter: https://www.reddit.com/r/Back4Blood/comments/qgjp2z/psa_disable_control_flow_guard_for_better/

Good luck

Duuuuuude, you've just made my game playable! Finally, thank you soooo much. Turning the CFG off miracly gives me stable 60 FPS. Love the games community, but its sad that people have to fix the games to made them playable insted of devs who gets paid for that. Thank you one more time!

Yeeeh, I tried here in VR gameplay.. And the microstutters are GONE when I disable the Control Flow Guard for the WRC.exe

The game there was awesome here before, but now? Amazing!!!!!

[Marc Collins]

I tried the AV exclusion--has no effect, though it seemed like a plausible notion.

I have an AMD CPU as noted in OP, so the Intel solutions don't help.

I will try the Windows Defender exclusion. [EDIT: Did not help.]

Thanks for all suggestions. We know who should have fixed this already...

Try to turn off disabling control flow guard (it's different than AV exclusion ;) it helped me a lot

Sorry, that's what I was calling the Windows Defender exclusion--you can get to that settings panel via Defender, though I realize it is not one and the same.

Let's be honest, the anti-cheat is a complete disaster. Even worse here, because I don't need or want it as I have no intention of ever running anything but single player in this game. Yet, it ruined what was a barely acceptable performance prior to its addition.

OMG this fixed it for me! Had this problem on AMD CPU NVIDIA GPU WIN 11 when playing on TV thru HDMI. No micro stutters after adding WRC.exe in Exploit Protection, "Control Flow Guard (CFG), Override system settings: OFF"
I'm so happy! Thank you and have a great weekend!

Switching Control Flow Guard off don't working for me. Like nothing else. I can say i try everything what founds in steam community, forums, reddit, etc.. of course my system is old already ( i7700k, 16gb, GeForce 4060 8GB ), but this is not a problem: proc usage 40%, memory 50%, graphics 60%, and FPS is stable 60. I can play whatever low or ultra settings and still have same micro stutters all way long. (Yes, car reflections is ultra low, mirrors off, crowd ultra low.. and so on) BUT. I suddenly find a cure. Maybe someone needs that too: at the start of the stage, before starting light, press ALT + ENTER, it switch game in windowed mode, and press once again to switch to fullscreen mode back. (working anytime. You can drive part of track with stutters, then do we switch, and they gone) For me this little trick works every time, and game runs smooth (maybe 1 or 2 small stutter in busy areas). I really don't understand the process behind that, but its working :) still hope Codies sometimes make game work for everyone. Still like it after spending half of a time in settings.

Anyway: thanks subjenna and Frey (HT off don't work for me too ;))

I will try this. I read of other similar procedures--just changing the main graphics setting and then putting it back--somehow resets something that affects the micro-stuttering. Again, ridiculous that these hacks are needed, but at least good if something simple works since EA can't be bothered to fix the core issues in the game being too busy selling DLC.

[DblM]

Yes, i forgot about this method, changing graphic settings works to. But with ALT + ENTER you don't need go to the settings, it's less annoying. But, again, you need to do it every time you start the race. Too much screens need to past thru for simple quick race :)

Certainly the problem is in the CPU. This game is very demanding on CPU side. And you go and say: But only uses 40%. Yes and No. You need to look per core usage on CPU. If the main two CPU cores (render core) have spikes at 80% or above.. you'll have stutters.

Even more newest CPUs have problem to run this game...

Besides that, another great indicator is your GPU usage, you don't be able to use all your GPU power, because your CPU don't keep up in this game.

Sadly, has no effect on the micro-stutters on my system :(

[Marc Collins]

I use a 144 Hz monitor, but only need frame rates in the 100 FPS range to be sure it is well above the frequency of the physics in the game. Cannot even achieve that consistently without turning everything too ugly. Vsync therefore has no practicable purpose, but I have noticed even though it has no effect on the micro-stutters, it does seem to help slightly with controller lag. The controller is happier with Vsync on.

There is another explanation for the micro-stutters I just remembered: Fanatec pedals attached directly to USB (not via a Fanatec wheel). Apparently some old bug among the long list they cannot or refuse to fix. That may be the issue, since everything else has been tried and graphics are good otherwise.

I'm not willing to uninstall the pedals since getting them back detected and calibrated is a pain, as is often the case with console-based games that don't deal with multiple controller inputs well. And, I can't do anything about it anyway...it will only annoy me more if I confirm that is the culprit.
