Have you never used the console before ever in the 14 years that JKA has been out? Open console by pressing the key to left of the 1 on keyboard. Type r_gamma press enter. It displays the current value. ---- As for web speed issues, I would power cycle the Modem and Router. (Unplug off both if you have both, then wait 30s, plug in modem, wait for it to have internet connection, plug router back in, let it get the connection to modem and your pc) Otherwise without knowing what you use its hard to say what is issue. Simply upgrading to Windows 7 will not make your internet slower, there is other factors that are likely instead.
