I'll leave a picture that explains about all of it. Happens regularly and I can't for the life of me find out how to fix it. As for the audio side, it happens every now and then where I hear sort of this electrical buzzing and it's really irritating.
That fixed the flickering problem but it made the audio one more frequent and the game slowed down a lot. I tried turning on speedhack to see if it would even it out, it did not.
Thanks. That dramatically improved my gameplay. It's now at a normal pace, no black or blue flickering. Although the audio issue is still there with the electrical buzzes. Usually only at the beginning of a level, perhaps that's the way it has to be, but if not, help would be appreciated regarding the matter.
Also, so I don't have to press F9 everytime I boot up the game, if I'm correct, I change my renderer from "Direct3D9 (Hardware)" to "Direct3D9 (Software)", yes?
