I want to forward this by posting a Reddit post where someone tried to help me fix my issue.
I have now tried everything I can think of to fix this issue.
In both Fortnite and PUBG, I experience game breaking stuttering, that is backed by wild frametimes. I have stable framerate and all of my hardware is working. In Rainbow Six and Benchmarks like 3d mark, I have no such stuttering.
1.Checked temperatures and clocks
2.Run stress tests and benchmarks
3.Installed games on an SSD
4.Reinstalled games multiple times.
5.Ran Windows Ram check etc.
6.Fully Reinstalled windows and formatted drive
7. Installed games on separate hard drives working separately and together.
8. Flashed my BIOS to the latest update.
9. Removed all hardware and cleaned
I ran an MSI Afterburner LOG of many Fortnite matches for frametime and they came back pretty erratic. As you can see capped a 60fps I am regularly hitting 50ms, even when my fps is stable. My frame rates are stable.
This is getting out of hand, it's like my PC is cursed and I have no idea what is causing it. I'm on disability and can't just start buying new components, because people have asked me elsewhere to try new hardware, which I can't. I saved for years for this PC and it's haunted!
Using third party frame limiter on Rivatuner helped somewhat on Fortnite but PUBG is currently unplayable.
