Various Graphical Problems

[Lamethrower 3]

OK So I'll say right off the bat, being my first post, that DayZ is an amazing mod. I understand it still has many changes to be made yet I would like to see if I can figure out a few problems.

So my issues are graphics related and most likely caused by software however It would be great to have some other perspectives on my issue. :)

The System:

• i7-950 @ Stock
  
• 12GB RAM
  
• 2x 560Ti SLI (Latest Stable Drivers)
  
• Storage = Over 9000
  
• Win7 - 64bit
  
• Latest DayZ builds
  

The Problem:

• Frame rates are inconsistent across different servers
  
• Intermittent artifacts
  
• Driver stops responding resulting in a black screen then continues to minimize the game leaving the game running in the background (I can hear myself running around) yet unable to maximize and see anything other than my normal desktop.
  
• Also one other minor problem is having a significant delay on the mouse movement which I have encountered in other engines and fixed by turning off v-sync, however, this did not solve that problem in this case.
  

Testing so far:

• So far I have tried a few different servers with the same settings and gotten anywhere between 60+fps to 20fps.
  
• Disabling AA and PP yields slightly higher performance but not as noticeable on the servers already giving bad frame rates.
  
• CPU load and temperatures are within acceptable levels (<40% load, avg 65c)
  
• GPU loads sometimes spike to as high as 100% however temperature remain at a max of 74c at any given time.
  

I have a lot more testing to do however I am currently at work so I will update as I go.
