Every 5-10 seconds I get a big stutter where nothing happens and then I get jolted back to where I should be. It wasn't always like this. I had frame issues after install and then I started passing -dxlevel 81 from launch options. I am using experiemental Nvidia 310 drivers on my GeForce 210 card.
I know its not a compatibility issue because it was working so great before. I noticed that my ping shoots up from 40ish to 300-1000 during these spikes. I am on N mode wifi and I get a solid 5ms to my router and 40ms to google.ca otherwise. I manually configured the interface so there is no network manager or other somesuch thing involved.
I have tried maxframes cfg, some FPS Banana tweaks and none stopped this hitching. What puzzles me is that it was working so well at first and then this cropped up.
My packages are all up to date. I also play Killing Floor with no such difficulties. I suspect this is a glitch in source!
