--- Comment #5 from dave.mueller-OI3hZJvNYWs@public.gmane.org ---
Perhaps you have to try with a bigger image (e.g. 4096x4096 pixel) to
compensate for your larger screen resolution.

I didn't played with the compositor so far, just used the standard KDE
settings.

I don't think that a second X session will do any good, as the system is quite
unstable after the crash and needs to be rebooted.

My NV17 also has 64MiB VRAM as shown below:
