I stopped playing mid season 2, came back for season 3, and I have this problem where my CPU gets locked to 100% cpu usage as soon as Overwatch is launched.
It is not my PC cause this issue is pretty random, I have to restart the game like 10 times in order to launch the game without that “bug”, when it’s fine I can play at 150+fps mid fights, but most of the times I get that bug and it is unplayable, when I move the mouse around, it’s like I have 0.50% sensitivity, I can’t move my camera, and there’s constant spikes.
I heard that some people get this cpu lock to 100% for around 5 minutes then it stabilizes itself, not me tho, I tried leaving my game opened for more than an hour.
I’m wondering what is the fix here? Is there any? I already reinstalled Battlenet/Overwatch.
I am having the exact same issue. The game was running smooth but for some days now whenever i launch it, CPU usage locks to 100%. After some minutes it goes down but still stutters. Sometimes it doesn’t even lower itself. I wonder why.
I’m having very high CPU usage since the last update as well. I checked to see if a setting was changed but it all appears the same. Last time I played was about 10 days ago and it ran without a hitch getting 180 fps (where I limit it) effortlessly. Now its all over the place, like a slide-show sometimes, and with very high 90% to 100% CPU usage. Can’t play like this.
The shader cache is possibly corrupted and shaders are randomly recompiling when you launch the game. Use AMD Software: Adrenaline Edition to Reset Shader Cache.
I’m running a Ryzen 5 3600 with PBO enabled, 16GB of CL17 3600MHz RAM and a Sapphire RX 6600.
I was getting very bad stutter despite CPU and GPU utilisation being well below 100%.
1080p capped @144fps low settings with drops as low as the 70’s reported via the game and MSI Afterburner but actual fps drops and stutter was far worse, felt/looked like 5-10fps.
I tried using the --tank_WorkerThreadCount 6 command line option to limit the game to 6 threads and I noticed the shaders compiled more quickly and the stutters mostly went away so I suspected it was simultaneous multithreading (SMT) that was causing the issue.
I disabled SMT in my BIOS and my fps are now rock solid @1080p with 270+ fps in intense team fights and 300+ fps when not engaged in team fights.
If you don’t want to disable SMT in the BIOS you could try using the program Process Lasso to disable SMT for just the Overwatch 2 process.
If you disable SMT on Ryzen systems the S3 state is disabled so you will not be able to put the system to sleep and will have to turn it off when not in use if you want to save power, this is a design limitation of Ryzen and cannot be removed with a BIOS update.
EDIT: I have to have SMT disabled in the BIOS and use the command option --tank_WorkerThreadCount 6 otherwise the stutters return.
