![]() I noticed after I did all that, but the stutter persisted after a map change, pressing Scroll Lock still mitigated it. HOWEVER, even assigning affinity to P-Cores isn’t as reliable as using Scroll Lock to park E-Cores (after turning on the BIOS option which enables that feature). So for a quick fix, if this happens during a Competitive game or something where you don’t want to restart the client, you can Alt+Tab, change Core affinity and/or Threaded Optimization to see if you can kind of get it to behave for a little while, but the main thing to do is restart the game (shut it down, change around through power plans, restart game). ![]() At that point, I closed the game, changed power plans around (to Balanced, waited, then back to High Perf), set Threaded Optimization back to Auto, restarted game, and problem was now gone. Then stutter was back, and switching Cores, Threaded Optimization/etc didn’t alleviate it. Until match ended and it restarted the map (this was Custom Game on Chateau Guillard with like 12 people). This made the rest of that game pretty decent. As a quick, temporary fix, I was able to Alt+Tab, assign affinity to only P-Cores, then go into NV Control Panel, turn Threaded Optimization to OFF, Alt+Tab back into the game, turn Reduce Buffering Off, Apply, then back on and apply, and stutter was temporarily mitigated (but still there). Best solution yet: Edit Power Plans to change the thread scheduling policy (See post further down this thread for instructions)ĮDIT: FOR EXAMPLE: So I just now got the issue where I started in High Performance Power Plan with Threaded Optimization on Default value of Auto, and I had stutter in-game.(Read more in my reply further below… sometimes this helps, sometimes this hurts, so try it both ways to see if it helps your problem) I am not sure if you have to restart to apply changes. EDIT: CONFIRMED, this WORKS: Another hail mary thing to try is turning off ‘Threaded Optimization’ in Nvidia Control Panel for Overwatch.exe and Overwatch Launcher.exe.Manually assign the game to run on P-Cores only, or enable the BIOS option which lets you stop using E-Cores by simply pressing the Scroll Lock key (may be handier if you don’t have a lot of other programs running while you game since manually assigning affinity is bothersome). Reduce Buffering: Turn it off and back on, especially if you’ve Alt+Tabbed.However, the main things to keep in mind for your graphics preset is to turn OFF Dynamic Render Scale and set one constant Render Scale yourself. I like using Razer Cortex to reset the profile because this does eliminate stutter even if only briefly. The main reasons to address that are game-related are: So there’s many reasons why Overwatch 2 may have FPS drops or slowdown or stutter. Many people may be alt+tabbing all the time and still not realize that it’s dropping your framerate by like 30-40%. I think you can just turn it off, hit Apply, then turn it back on and hit Apply again while staying in the menu and without going back into the game, like in OW1, but you’d have to test that out.Ĭan’t believe that’s still a problem all these years later. EDIT: You may have better results only assigning it to the physical P-Cores (Cores 0, 2, 4, etc so in an 8 P-Core system, the 8 physical P-Cores are Cores 0, 2, 4, 6, 8, 10, 12, 14 and the ones inbetween are hyperthreaded).Īnd most of all, and many people may remember this from OW1, pressing Alt+Tab then going back to the game may create stutter or severe FPS drops which can be resolved by going into the game’s Options, turning Reduce Buffering OFF, hitting Apply, going back to the game to make sure framerate is back up, then turning the option back on (because it helps reduce mouse lag so you need it). I’ve tested it and it seems to work, because then hitting Scroll Lock to park/unpark E-Cores doesn’t seem to do anything. But a few minutes later, the st…Īn easier and better way to deal with this issue is to ALT+TAB after you’ve started the game and manually assign affinity to the P-Cores only in Task Manager. So first time I enabled it mid-game, nothing happened. So I finally decided to try enabling the BIOS option which lets you ‘park’ the E-Cores by pressing Scroll Lock. ![]() I could go days without it but then it would come back. My original post: Stuttering started out of nowhere a few days agoĭespite all that I tried, I still occasionally got the stutter.
