I had limited the length of the freeze using Nvidia 3d settings. But I use performance settings and signal is not passing through other processes. I did see a glitch type freeze after using this tweak but nothing to complain about. IN other words I'm might be one more step to faster glitches instead of 2 second freezes.
The are infinite variables in troubleshooting this issue.
1) It's not secluded to AH, a lot of the reading I did was from other game forums or about other full screen games.
2) We can't nail it down to hardware because nowhere I look people actually post their hardware, except a few here,.. like is it totally Nvidia, DX or Windows related.
3) Not every freeze seen by others is caused by the same issue nor same type of freeze. You may fix one issue but others still remain.
Yipi has a good idea to use AVG or Ccleaner to optimize and put processes to sleep. They are both similar in what they can do, but both make it much easier.
Point being, it's a complicated issue to solve.
