thought up a possible work around to the renaming directory thing.
in the wickedgl folder there is a file called wglgames (not sure what version i have..might be different). Copy the quake 3 line..paste it in there and then edit..
not sure if it would work..havent tried it..i did enter a fake game name using above method and then ran wickedgl install and it showed up on list of games.
i might try later.
What i really want though is the ability to switch in-game from my geforcemx2 to my V2 sli's (and u though v5 was old...ha)..want to be able to test both..see which is better for me tweaking wise.
