FPS problem persist

I did as technical support told me. I updated my OS and graphics card driver but my fps still continue to dip below 20. Had it at 60 before the latest patch

No idea what to do now

Have you tried this guide? GUIDE: Maximizing System Performance for Overwatch (PC)

yeahh i have the same issue, my fps are stuck at 18 even though before the patch they were always between 60-80, idk whats causing it and lowering the graphics to minimum does absolutely nothing

Yes i have to no luck sadly

Try reverting to 399.24 graphics drivers, if you have an nvidia chipset/card, newer ones possibly cause drops.

If not, reinstall windows? Make sure there are no weird overclocks being done? idk honestly
