FPS in cs:go limited for no detectable reason

[Schnasty]

HeyGuys

My current PC has following specs:

• AMD FX 6200
• GTX 560 TI
• Corsair CS 450M
• OCZ Vertex 3
• GA-970A-DS3P
• 2 x 4GB G.Skill RAM
• Windows 10 64bit
• edit: BenQ XL 2411 144hz

And here is my problem:

On this PC I mainly play cs:go which runs fine (>200fps) on 5v5 servers.
But on DM servers with +16 clients my PC doesn't really start to struggle, but my frames do (stable 90fps).
The utilization on the first CPU thread is at ~65% with the rest of them chilling at ~50%.
My GPU utilization never reaches 60% even on 1920x1080.

Here is what I have tried so far:

• checking temps. - all great, not in throttling range
• formating my SSD and try a fresh windows
• trying all these little "fps boosting tricks"
  https://steamcommunity.com/sharedfiles/filedetails/?id=268030869
• turning off 3 cores and OCing the 3 other cores to 4.5Ghz
  it then utilized all CPU threads to ~70% with no change in frame rates
• changing my resolution to 800x600
• changing my energy options from balanced to maximum performance on nvidia control panel and windows

All this had no real effect

 

Now I need your help.
What does limit my frames?
Do I need to upgrade my old GTX 560 even if it is not utilized at any given moment?

Just tell me what you would do if you had these problems.

Thanks!

I am aware about the hitbox changes that happened a while ago which also screwed the FPS for some.

These changes motivated me to play the game again.

But my FPS were always bad, with the hitbox change I maybe lost 20 fps at max.

as long as you're running at 60hz, then what does it matter?

1. I forgot to mention I play on 144hz, sorry

2. even with 60hz monitors it would matter.

When did this start?

When did this start?

When I got my 144hz monitor I started to see these fps drops more clearly.

But it started with the first time playing cs:go

Can't anyone atleast tell me which CPU/GPU he has on which fps ?
