[SOLVED] GPU High Usage, Very Low Performance

[yullbarez]

Hi, i have Sapphire R9 280X Tri-X OC 3GB GDDR5 384-Bit. It recently performing bad for some reason. I've tried 5-6 different drivers but can't fixed this problem. First of all, i've been getting 60 FPS on V-Sync on GTA V(Very High, AF X16, RMSAA X8, FXAA ON, MSAA OFF, 1280X1024) at %40-50 GPU usage.

Now it's dumped down to 25 FPS avarage at %90-100 GPU usage for some reason. I've been also getting much lower performance on every other game i've been playing.

GPU is running perfectly, there's no artifacts, crashers or something like that.

GPU can't even perform like GTX 750 at this moment.

I think it started to happen after an mutliple WattMan errors i've got about 5-6 days ago.

Even on Terraria, FPS drops to 40-30 FPS and GPU usage so high on this Game. Even my old HD 3650 was getting 60 FPS on this game.

GPU Drivers i've tried to hoping to fix this issue: Adrenalin 2020 21.1.1, Adrenalin 2020 20.9.2, Adrenalin 2020 20.4.2 and Adrenalin 2019 19.12.1

GPU Even runs at it's maximum clock speeds in destkop.

Specs:
CPU: Intel Xeon X5450 3.00 GHz
MB: Asus ROG Commando
GPU: Sapphire R9 280X Tri-X OC 3GB GDDR5 384-Bit
RAM: Kingston 6GB DDR2 800 MHz CL6 2X 2GB 2X 1GB

What should i do? What causing this? Are you witnessed something like this before? Thanks in advance.

I'd look for a mining virus. 100% load on the desktop is the clue. I'd also look at temps, voltage, and clock speeds. Make sure it's running like it should.
