I'm sorry if this is too long, but I tried to be thorough.

Cs go maxes out at 230 fps when absolutely idle (source engine fps) and has an average of 150 fps (min 100) in ALL game modes (30man server, or 1v1 against a bot). This is significantly lower than expected.
150 fps is barely playable (100 is NOT) but anything over 200 is perfectly acceptable, to describe a range. Recently I changed the graphics settings in the game DOWN and noticed a loss in fps (180 average to 150 average), which could not be recovered by reverting back to previous settings OR default OR lowest possible settings.
I know that csgo is a cpu intensive game, but I would not expect my i5 to be bottlenecking at <200 fps with low temps. Furthermore boosting amd settings seems to handicap the fps even more (from what I understand, and I can be totally wrong, these things like FXAA are entirely handled by the gpu and not the cpu). If by turning fxaa on, I get a 20 fps drop (average), this seems to suggest the gpu as a bottlenecking culprit (because such a big decrease, if handled by only the gpu, means that the gpu was already quite taxed) , which makes no sense because its a 290x and lowest settings+fxaa should not be so impactful
Furthermore others with inferior gpu (particularly AMD radeon cards) and the same i5 cpu have reported greater than 210 average fps during gameplay.
The usual suspects:
CPU usage hovers between 20-40% during gameplay.
No processor is being parked.
Multirendering is enabled (resource monitor reports all 4 cores working during gameplay--and due to gameplay, not other apps)
testing was done with -high (launch option for high processor affinity) and without (my usual), no difference was seen
CPU temp is 43 @all cores averaged over 20 mins of gameplay.
GPU temp is between 46-51 celcius with an average of 50 (sits at 50 consistantly). --well within 290x ezmode temp ratings
Tests were run at absolute lowest game settings @1920x1080 (am not willing to change resolution) (NO vsync)
Catalyst cs go profile is manually set to allow application settings
I play the game in windowed mode (-noborder -sw launch options) on 1 monitor (I have 3 in total operating during the game)
