The video listed in the staff comment is showing evidence that I have no input lag on certain games. Games like Doors/High Texture/non owned games seem to break my inputs and add a lot of latency/lag, while other games seem completely fine. I have no clue how to reproduce this, but has been happening with restarts/other
Expected behavior
In the video provided, the evidence is clear, it should interact more like the first game, and not the second. (Only started happening last night)
My only observation is that some inputs in games are handled server-side. If you have a high ping this can result in a seemingly large input delay while in reality it is just taking that long to relay to the server.
I had sudden input lag issues recently too but what seemed to work for me was to go to Windows Settings > System > Display > Graphics and turn off Optimizations for windowed games for ROBLOX in the list below
