What am I supposed to take from that picture? It leaves so much info off the table, that it has me confused...
Oh wait:
3D Mark Timespy Physics Score: 13579, 12213, 10958, 9673...
The Physics Test is one part of the entire 3D Mark test.
That's misleading as all heck. Bad Google Search, bad!
I gotta break this down - pardon the multi quotes:
my cpu is overkill for csgo?
If the game engine only utilizes 3-4 cpu threads, a 10850K has 20, and CS:GO is all you play...
i could get better cpu that would give me better performace for csgo?
This cpu is darn good already - the best out of box performer of Intel's current lineup, which is no slouch at all, by the way. Ryzen 5000 is the only thing that would give it any competition at the moment.
(maybe OC my cpu to 5.0ghz?)
When CS:GO is more dependent on single thread performance, that would do more harm than good; the 10850K can boost up to 5.2ghz when it isn't fully loaded. You won't see that kind of boost behavior when running 3D Mark or most other stress tests.
I can't help you there, as I'm not THAT familiar with this game. What little I do know about it:
1)The already mentioned low thread usage
2)Some competitive players take this game, drop resolution to 720p and 4:3 aspect ratio, and max out the draw/view distance to maximize fps. This makes the game even more heavily reliant on cpu single thread performance and ram frequency(3200+) and timings(lower is better).
3)The gpu doesn't matter as much either. Even less so at 720p res and 4:3 AR.
4)Valve's Source Engine, which CS:GO runs on, actually
favors AMD cpus. No, I'm not telling you to go out and change your hardware. Yours is still fine, you likely just need to change some settings, though I don't know what all of them are.
i know csgo is mostly using the cpu, more than the gpu thats why i wonder how come my cpu is so low usage in game
I already told you why: 3-4 threads out of 20.
When you look at cpu usage on the HUD, it's showing usage of the cpu as a whole. That's not the accurate way to do it.
