To be technical here’s a list of troubleshooting steps that I think will normally resolve something like this. If I missed something please let me know nicely. Please don’t forget respect.
- Update Graphics Drivers
- Roll back the last update
- Disable Windows 10 Game Bar
- Disable Windows 10 Gaming
- Windows Settings > System > Notifications & Actions > untick Get tips, tricks and suggestions as you use Windows
- Perform a clean boot
Now most like myself have done all of the above AND still getting low FPS in games.
I always think of others so once I find something I will report back to what it is and whether or not it will help others that are experiencing this same issue.
