A while back in a alpha from a difrent game some one came up with the tip to run the game in sandboxie im not sure what the progam dos but this workt realy well for my performance So today i decided to try this on PA since after 20 mins of gameplay i got stuck on 10fps This somehow workt out great and i now got 40 fps in the heat of battle Short tutorial..... Download and instal sanboxie. Start sandboxie(not the browser thingy) Drag your PA shortcut in to sandboxie and run the game in sandboxie. Steam users will need to login to steam again. Not sure about the PA launcher Hope this helps some ppl cheers!
If that's true it might offer some interesting performance hints to Uber. Offhand I can only think of disk access caching as a benefit, but it actually touches a lot of stuff. http://www.sandboxie.com/index.php?FrequentlyAskedQuestions#HowItWorks
Well its a beta so i think they are doing a great job i mean it runs stable (for me atleast) But this is just a temp fix to get the frame rate up
