Question Something causes low usage/wattage on gpu

[Social_gamer]

This is a friend's pc that he just upgraded, previously there was a 6500xt and a 2600x.We started off by updating the bios to f32, then the ec fw update tool, then to f40 and finally to f65.
After all that we were excited to try cs2 since that is my friend's main game only to find horrible performance at 1080p all low 120-150 fps and a gpu usage of 50% and the max power draw at 55 watts(The wattage was tested with amd adrenaline and the fps with in game capture+amd adrenaline+afterburner, no Vsync, no limiters,latest amd drivers),uping the settings to high we saw no real change other than the usage that was max 62-63% and the wattage still the same.We also tried this with league of legends and while at the start we got a nice 400 fps it then dropped close to 240-260 at medium settings and the same 50% usage and 55 watts.We tried verifying the steam files,deleting shader cache and most easy "fixes" we found on the internet but nothing fixed the issue.At last we tried the "Stress test" on the gpu at amd adrenaline and showed the 7600 going steady at 150-170 watts power draw for more than 2 minutes, so I crossed out the psu and the gpu.🧍‍♂️To summarize bad performance in games, 50% usage and 50-55 watts consumption 🧍‍♂️All help will be appreciated!

Using about 50% of GPU when playing CS2 is normal, it's a CPU&IO bound game.
Getting low FPS in LOL is also normal, you should run another normal-weight game to let the GPU know that it isn't handling a wallpaper-like easy job. My friend once get 60 fps for 20 seconds every 1 minute when using 7700xt due to the load is too slight for the GPU. I asked him to run another game when playing LOL, then the problem disappeared.
