Why do I suddently not have GPU Acceleration?
Are you using one of the "unsupported" CUDA cards? If so, you need to reapply the CUDA hack since the update overwrote the file you had manually modified.
What card are you using?
In general, it helps if you give information about things like what hardware you're using when you're asking a question about your hardware.
Should have mentioned I have the GTX 285. I just installed the latest update for that card and now everything seems fine. Thanks.
