[solved] debian nvidia gtx 570 low frame rate/mouse lag - Loafers - 01-10-2012

recent installed debian squeeze on my box and upgraded my kernel to 2.6.39-bpo.2-amd64 since my usb wifi card depended on a module that was only in newer kernels. since the kernel was backported, i couldn't install the nvidia driver due to missing files/changed filepaths or something like that.

then i found a solution. followed it and installed nvidia-glx from backports

did nvidia-xconfig rebooted my comp and everything worked fine.

started up xonotic-linux64-glx and everything seemed fine but occasionally the mouse would lag for no apparent reason then work fine the next second. next i joined a game and noticed the frame rate was absolutely unplayable - everything was in slow motion.

any ideas on what the problem may be?

some additional info:
loafers@debian:~$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  275.36  Sun Oct 16 21:53:01 PDT 2011
GCC version:  gcc version 4.4.5 (Debian 4.4.5-8)

turns out i can't watch a streaming video while playing the game or the problems above will happen.... really odd... o well
