I got a new computer, Intel Core i5-3350P, CPU @3.10GHz. 64 bit windows 7, and an ATI Radeon HD 5450 graphics card. And it's a great computer and all for me, but when I try to download games, like eerie or kraven manor, the games are unplayable. I open up the game and it downloads just fine and is allowed in the firewall and all but the UDK banner pops up, a black screen comes up, and then it minimizes and makes a load in noise. When I try to open the minimized game it just opens to the black screen and re-minimizes.
Help please, I just want to play my games
I download my games from Desura, Gameshed, and other websites.
I believe it has something to do with UDK games because whenever that banner pops up the games never work...
