If Win7 wait for Blizz to fix their code.
If Win10;
Start menu-> Control Panel-> Hardware and Sound-> Sound-> Right click your playback device-> Properties-> Spatial Sound. Turn it ON.
Launch Overwatch, your fps is back to normal. If the sounds bother you (they are really bad), you can turn Spatial’s off ingame. Your fps will stay normal.
However, you need to repeat this every time you launch Overwatch.
Then nothing you can but wait and hope Blizz fixes it. Logically they should soon, considering how many people have the issue. I’m having faith that it’ll be patched today. I feel you, I’m in a similar situation.
I’m having more sever problems. 100fps on all low settings @ 1080p. IM NOT TROLLING.
Hardware is all the same. 2080ti, 8086k, etc. Not sure what is going on right now. Maybe because I have it hooked into an elgato HD60Pro? Super annoying.
I have the same problem with my PC, except worse, I get only 30-100fps on my RTX 2080 paired with my core i7 9700k (5.1ghz) with 16gb ddr4 3300mhz memory, with my aorus z390 motherboard. I still get 300fps in the training range of I lower the settings, but same result regular play
