I had tried playing Dota 2 last night with my new rig just to test how much the graphics would differ from my old one. Upon launching it, I noticed some white horizontal lines appearing in the screen and only in the game. Researching the problem, people seems to have been complaining about the AMD series and this particular problem for a while now. But in some cases, people had already fixed this problem. I was wondering if anyone would be familiar with this and could help me with it. The rig's GPU is a HIS Radeon HD 7850 and the monitor is a 19" LG one with only VGA. I am using a VGA to DVI converter that was included in the GPU box (the screws are a bit loose on this one so maybe this contributes to the problem?), I already had downloaded AMD's Catalyst 13.5 but it didn't solve the problem. Currently losing confidence on AMD cards now. Probably should've bought a 650ti Boost instead. I prefer not to give up on the GPU though if possible.
