Testing the impact of 100% vs 80% gpu utilization on input lag. Based on the guide by the creator of Frog Pursuit. He's confirmed that maintaining the 80-90% gpu utilization window is critical to input latency.
In Tp4's testing, even in a racing game that is doing 315fps. One can feel the difference in input latency.
At 100% utilization, when counter steering, it feels like you've over compensated, and need to release, but then right after you release, you again feel like you're too loose. So it's a weeble wobble effect.
Whereas, at 80% utilization, same 315fps (lower settings), the immediacy of input gives you alot of confidence in the Exit Line.
