So I've reformatted and installed Windows 7 Ultimate. Everything starts fine, but gets progressiveness worse after about 10 minutes of play, and I left it go for an hour once, and it was REALLY bad. What can I try? Is my video card failing? Are there some other drivers I can install? This isn't normal lag from maxing out the card, it I can't figure out what suddenly caused this other than some obscure difference between the consumer preview and the retail version. I've tried installing beta graphics drivers, re installing the operating system, re installing the bootcamp support software, and freeing up space (I have about 20 GB free). I can turn the graphics down to 800圆00 with no antialiasing and low texture quality, and it runs much smoother on the 'up' motion of the cycle, but every second it moves back into this lag spike. It's a cyclical lag that comes and goes like clockwork. Every second Skyrim and Crysis alternates between running smoothly and lagging. This laptop has an Nvidia GeForce GT 650M graphics card inside, it runs great.īut I recently replaced my Windows 8 consumer preview with the retail copy, and since then, 3D games lag in this odd way, no matter what the graphics settings. The two games used to run super smoothly even on nearly maxed out settings. I've been playing Crysis 2 and Skyrim on my Retina MacBookPro (10,1) for months now.
