With windows 7 when you change the visual effect settings to adjust for best performance it also changed the GUI to look like win 98 and it gave me 15-20 fps increase in every game. Now i do this with windows 10 and it doesn't change the GUI to win98 and i have 20 fps less in every game now. Is there any way to change it? If not i think i will have to install win7 again... But i really like win10 because it's faster on other things except gaming.
