I've had my Sager NP8170 laptop for almost two years now, and it has always had extremely high performance in games. Perfect framerate in 1920x1080 in just about everything I played. But today I booted up Dark Souls after not having played it for a few months and I barely had 15 FPS! I downloaded the resolution fix for it, but that just made it go from bad to worse. Worryingly, I checked other games and sure enough games I used to play perfectly now have 15-20 fps. I'm extremely worried, as my computer has never given me trouble like this before. I dusted out the fans and heatsinks not too long ago, and the temperatures for my cpu/gpu aren't getting high while I'm playing these games. I even tried updating the drivers to no avail. Please help me!
