Disabling Hyperthreading (i3-6100 dual core + ht) seems to have worked for me thus far, and I’ve been troubleshooting since release! This seems to be the most effective workaround, so there may very well be a dual core CPU issue. I also suggest if you are using an AMD gpu like I am (RX 470) make sure to download the latest BETA driver from AMD to version 22.10.1 (non-whql) as it has specific optimizations for Overwatch 2!
You can TRY setting the affinity on overwatch to only use the 2 physical cores and not the logical cores (hyper threads) but that method still resulted in a crash for me. I think you have to physically disable HT as some have suggested in the bios, but if you want to try for your system to manually set which cores your application can run then follow these steps:
- control + shift + esc
- right click Overwatch (must click more details bottom left)
- click ‘goto details’
- right click 'overwatch.exe"
- click ‘set affinity’
- select only physical cores (for Intel it’s ‘core 0’ and ‘core 2’)
Blizzard are going to have to fix this as I don’t think it’s a GPU driver related issue, good luck!
