Low GPU usage while gaming

[IIGodlikemode]

Hello everyone , i have been having very low gpu usage when gaming even with everything maxed out it never goes above 40 % and only for like 2 secs , and my CPU is working harder mostly only 1 core is making all the work ill post screenshots of when i was playing csgo with everything maxed out also i set everything to default on nvidia to see if it would push the gpu more but it didnt same as if i was playing with everything on low and i see people with the same setup benchmarking on youtube and they have like 60 % on all cores and gpu is like min 60 % up to 80 %

Are you still getting your desired fps?

yeah im getting 200 + fps but the games still feel laggy  and i think maybe it might be because of that because i tried everything else and cant fix whatever is causing my games to perform bad despite having high fps
