Microstuttering + choppy, skipping frametimes

Interesting note - after a bit more testing, I've discovered that the CPU affinity 'solution' (unchecking CPU 0 and only leaving CPU 1-3 checked) definitely gets rid of the stutters and frame drops (even on maxed Ultra setttings), but it WILL eventually (after about 10-15 minutes of playing) lead to the game's framerate completely tanking into the single-digit numbers at some point. What's peculiar is that at that moment, my wireless Xbox One controller will also lose connection and the game will ask me to reconnect it. I'm not sure whether the controller losing connection is a result of the game slowing to a 3 fps crawl, or the cause of it. Maybe the CPU 0 core handles something with regards to the controller and turning it off leads to the controller losing connection and tanking the game's framerate?

Changing power usage to Maximum performance in Nvidia CP didn't help (it was initially set to the default Maximum power, not Adaptive, for me).

Honestly, I don't know what to do now. Stuttering is really obvious and experience-ruining on certain tracks, and the CPU affinity trick works for about 15 minutes, but then seems to completely choke out the game, with me needing to restart the event or the whole game...

Some more feedback:

I didn't have MSI Afterburner running when I experienced the issues, but just in case, I removed it entirely from my system and restarted the PC. Still the same problems.

I've also tried (according to advice from one player with similar problems) setting both my Nvidia GPU to Max Peformance mode (from the default Max Power) in Nvidia Control Panel, and setting my whole PC's power plan from Balanced to Maximum performance in the Windows 10 settings. Neither helped. The only reason I tried the latter is because I had a sort of similar, Windows 10 related issue a few years ago where the game Bulletstorm; Full Clip Edition would refuse to run at more than 50 fps with Vsync on, but changing the system's power plan to Max performance would fix it and enable the proper locked 60 fps framerate.

I can't try a wired Xbox One controller yet, but I tried playing the game with the keyboard for a bit (controller wasn't even turned on) and experienced the same problems, so it doesn't look like it has anything to do with the controller.

Can't check my PSU's specs right now (I'll open the case and post them later) but it's just over 6 years old at this point, like the CPU and the motherboard. I doubt it's a failing power supply, since I've been running newer and more demanding games (like Doom Eternal) perfectly in recent months.

Also, another important symptom I forgot to mention - the game's menus that feature in-game roads as backgrounds seem to be locked at 50 fps most of the time, and in some cases, even the actual gameplay is stuck at 50 fps (though the frame limit is 60) until I restart the game or change the graphics settings from one preset to another and back. 

The magic CPU affinity trick (disabing the first core of the 4-core CPU) that I mentioned REALLY temporarily fixes all of the above issues - both the stutering/frameskipping and the 50 fps cap in the menus, but unfortunately always causes the game to almost completely lock up after 15-20 minutes. It's the EXACT SAME issue and workaround that was apparently noted by many players in the PC version of the original game, only the solution isn't quite working for me.

Hopefully this is enough information and the development team can get a good patch out to fix it, it's really souring my experience. And it's even more grating that it seems to be an issue carried over from the 2010 PC release.

you dont have to worry you are not alone with this, i have an i5 9400f, gtx 1660 and 16gb ram and i can barely touch 60 in game, this game is just poorly optimised, im surprised no one talks about this.

I've put the game on the backburner until this is fixed as it's really impacting my enjoyment. Please fix this. This was already a fairly premium price for a very low-effort 'remaster'. At least have it run well.

Okay, so I seem to have found a working solution for this. Fiddled around with the CPU affinity trick and some other settings, and I've been able to find a combination of settings that allowed me to have three 1h+ sessions with no stuttering, a perfect, constant 60 fps and no game freezes in the last couple of days. It also seems to simultaneouly solve the problems with skipping/stuttering/crackling audio that is likely the result of the same issue.

Alt-tabbing out of the game when it's been running for a few minutes in the main menu and turning off the first CPU core  (CPU 0) in the game's CPU Affinity settings in Task Manager while leaving the rest active is indeed the fix that solves the issue. Keep in mind that this is apparently the very same bug that the original HP2010 had on PCs (at least the Steam version), so the Remaster just carried over this issue and it's likely a part of the game's core code. I really hope and urge the EA representatives on this forum to forward this issue to the dev team, as it's a 10-year old bug that hasn't been properly addressed, even though it's well documented on various online forums.

Other settings: 

- Power usage in in Nvidia Control Panel's profile for the game: High Performance (might be a placebo, but I'll just leave it as such)

- in Launch Options for the game in Steam's Library, I put '-high' (High CPU priority for the Steam version of the game)

- Borderless Windowed mode in-game

- Vsync On in-game (didn't force it through Nvidia CP)

- Max quality graphics preset in-game

The best part is that the secondary problem with the game totally locking up after 10-15 minutes while using the CPU affinity solution is apparently also gone, but I'm not sure what party of my toying with different other settings solved it. It might have been the High CPU priority launch option in Steam, as I'm pretty sure that after adding it, I've had no further issues. If you don't have the Steam version of the game, maybe try increasing the game's CPU Priority from Normal to High or Real-time in Task Manager (besides unchecking the CPU 0 core in Affinity).

Overall, while the game is now very enjoyable and I can finally start playing it properly, I really feel like PC players shouldn't be expected to try all these ad-hoc solutions themselves, and for the Remaster to be plagued by the same obvious technical issue that the original game had a decade ago.

Nice find!

You can use a program called Process Lasso to permanently set the priority and affinity. Like you say though, this is not a permanent solution and needs to be fixed.

It has been more than 10 days since launch and EA has not yet released a fix. This is disrespectful to those who bought the game at launch. 😕
