Hey all.
I have a Lenovo y570 with a Nvidia Geforce GT555m. I just recently bought GTA IV on sale from Steam, and I'm having the same issues with it that I was having with Crysis. I originally thought my system wasn't beefy enough to run Crysis but after having the same issue with GTA IV, I've come to believe its caused by Optimus.
When I play either game, I have initially start out with high FPS but in Crysis, it drops after a few minutes to under 20. With GTA IV it happens instantaneous. When I selected Benchmark on the GTA IV graphics menu, I noticed after the benchmark that the game was only recognizing the Intel HD graphics. I assume this is the issue with Crysis as well. It seems to only happen with older games, HL2 included. Doom 3 runs off of the GT555m no issues.
I have tried updating to the newest available drivers and selecting the games individually from Nvidia control panel but neither helped.
Anyone have a fix for this?
