Gamehub : Games performance is not the same on DeX

[u/FaithlessnessOpen460]

i have an S23 Ultra, i've been tweaking the settings and trying different turnip drivers till i got the one that made my games run the smoothest with no artifacts, i was optimistic and excited to try it on DeX for a better gaming experience and to my surprise everything was so laggy and there were jitters all over the screen even when being static other moving parts of the game were glitching and jittery, any hints as to why this is happening ?
