suppose the base input lag is 0 (i.e. uncapped has 0 input lagspacediver wrote:just so i'm following on one of your lines of thought:
assuming equal base input lag, over many measurements one would expect the same distribution of input lag in both these situations:
1) artificially capping a game at 125 fps (when uncapped it could do 1000000 fps)
2) a game that can only render at 125 fps even when uncapped
correct?
for 1 you'd get anything between 0-8ms lag
for 2 you'd get anything between 8-16ms lag
this depends on the cap working by sleeping after drawing instead of sleeping between getting the input and drawing.
