Question Low FPS in CS:GO after computer rehaul

[the_red_spirit]

Recently I upgraded my PC and my specs changed from :
AMD FX 6300
2x2GB Vengeance LP 1600Mhz + 2X4GB XMS3 1333MHz
Asrock 970M Pro 3

To:
Intel Core I5 10400F
2x8GB G.Skill Aegis 2666MHz
Gigabyte B460M Aorus Pro

I simply removed old components and installed new ones. I didn't reinstall Windows, but I did use Device Remover to "remove" old hardware and installed all new required drivers for board. PC is seemingly perfectly functional and I have tried out some demanding games on it. These are GTA 5, Crysis (original), Far Cry 3. I also tested I5 in BOINC. Everything seems to work perfectly fine, except CS:GO. In CS:GO I get very low FPS for no obvious reason. Visual settings weren't changed and I get 20-30 FPS in both online and offline matches. FPS seems to become good in tunnels or other very short distance areas, meanwhile in commons places game is really unplayable. I reinstalled graphics drivers (RX 580 8GB) because I thought that it could be some driver conflict. I rechecked CS:GO file and there were 2 bad files. I straight up uninstalled and installed CS:GO. Tried disabling Hyper Threading in UEFI. Reinstalled WiFi card. Checked component temps in stress tests, they are perfectly within limits. But still I get abysmally low FPS in that one game. It's really frustrating to get way lower FPS than with FX 6300. What could possibly be wrong with this computer?

There's no need for that as everything is working fine, other than CS:GO.

It seems that I had left in game MSAA set to 8X and in AMD control panel I left supersampling instead of MSAA. Once I set them to 2x and MSAA CS:GO runs perfectly fine.

Regardless of your later post, there is usually every need for that.
