Re: Poor 2D Performance
I acutally found a pattern of the performance of FF and KE4:
When the GPU temperature is low (PC is fresh bootet; was off for some hours) when the nvidia driver is loaded, the performace is bad. My GPU temperature in this case is about 37°C.
When the GPU temerature is higher (for me: 50°C+) when the nvidia driver is loaded, the performance is good.
I think there is a bug in the driver initialisation.
