try changing the sensitivity and putting it back. it works for me. If you have problems with the game go to the steam library and go to local files to browse local files. right click on gta-vc and proprieties and select compatibility and select the game to run in windows xp and select run in 640xsomething :) it works for me very well on windows 10 . 399 392 0 63 179 161 217 160 267
