does GPU bottleneck cause input lag ?

Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

does GPU bottleneck cause input lag ?

TLDR : Can severe GPU bottleneck cause input delay ?

Hello, hardware newbie here !

I recently upgraded my setup with a new CPU and RAM but not my GPU as I usually run games on low res low graphics so figured it would be useless, and on my new config I have very good frametime and no stutters, but noticable input lag (more appropriate to call it input delay)

only Nvidia low latency mode on ultra makes a HUGE improvement, and maybe even more when I cap my frames in game.

BUT there is still input lag remaining, tried windows resets and multiple windows power settings and nvidia scaling settings but nothing make my aim feel the same, its not as snappy as it used to be.


Can a Hardware connoisseur tell me if severe GPU bottleneck can cause input delay ?

specs :
-Asus Dual RTX 4060 Ti
-ryzen 7 7800x3D
-32 gb ram 6000mhz
-B650 MSI
-corsair PSU 850W

just for reference in cs2 with low res low graphics my CPU is barely at 30% and GPU can reach 100% if I dont cap fps

Thank you for your help !
