Adopt a systematic approach with proper testing methodologies instead of just blindly changing many settings at once. Create a personal document and keep track of everything you do.

However, it is useful to be aware of things that can impact user experience and adjust them according to your needs. Due to the sheer complexity of hardware and software and differences between various architectures, your mileage may vary."In all studies, the trend shows continued improvements all the way toward zero latency."."The average difference in aiming task completion (the time it takes to acquire and shoot a target) between a 12ms and 20ms PCs was measured to be 182ms - that is about 22 times the system latency difference.".Visual demonstration of 1 vs 10 milliseconds."While participants performed dragging and scribbling tasks, very low levels of latency could be discriminated, i.e., ~1 versus 2 milliseconds while dragging".
