Low fps

Hello,


i play cs with 110-150 fps .

I have an amd ryzen 2700 processor and 16gb 3200mghz memory modules .

Why doesnt it run at 300 fps ? I have low resolution and everything set up to low , i also have enabled the command fps_max. What else should i do? i mean my fps are 300 in an offline map but when i play comp they are never above 200 never never.
Please try to reply only if you know.
