you can use beta patch's with steam, the patch is in its own mod folder with a beta exe

the latest beta patch removes the need for the -winxp tag :)

thanks a lot :), you guys are doing a great job, once i get my ssd i'l start playing again :D

vram dection still dosnt work, still reads wroung in my cfg even after deleting it forceing arma to make a new one but i dont need to add anything to the shortcut and there is a peformance increase of about 5fps for me

Even if they could add a option to put our correct values in for the game to use i would be happy, cause even with the -winxp, the game still thinks i have 2gb vram when i only have 512mb and that would have to be causeing problems. the game runs fine on my win xp 32 boot, i get loss of frame rate and crash's every 10 min of playing on my win 7 64 boot when it seams my gpu vram is full and i get a lot of white objects befour crashing

q9650 8gb ram 9800gt win 7 64 rc/winxp 32 unplayable on my win 7 boot even with the -winxp tag, 15-30 fps but the game crashes every 10 min or so on the win xp boot it runs 30+ fps on last mission with higher detail than win 7 boot and dont have many issues. i'v got a ssd, win 7 retail and a hd5870 on the way so i'm gona put the win 7 and arma on the ssd and try again when the next patch comes out. this game still needs a lot of work, for now i'm just playing a1 untill a2 is better

It seams to be a v-ram dection issue, this is what i worked out.

I recently read Bug #4042 A2 Community Issue Tracker about VRAM Detection Broken http://dev-heaven.net/issues/show/4042 I have noticed with my system when going between 32 bit and 64 bit windows (duel boot xp 32, 7 64) that the more ram the system has the more it allocates to be used as vram, I checked dxdiag and it said my 9800 gt has 4080 mb of vram, I then checked the 2 lines in the arma.cfg. localVRAM=2139150848; nonlocalVRAM=2139150848; I then added these two together (they are the same) and converted it to Mb which was 4080.10645, the same as what the dxdiag shows my vram as. It seems when arma2 checks your vram it gets your total and halves it, meaning the more ram you have the bigger total ram you have so arma thinks my 512mb card has 2gb vram, which was causing crashes every time I was in a town or graphic intensive place (the buildings and the ground flash white and then the game crashes straight away) I converted my vram of 512 to bytes 536870912 and subtracted that from my total vram 536870912-4080.10645=3741430784 Then I changed my arma2.cfg localVRAM and nonlocalVRAM to end up with the following: localVRAM=536870912; (GPU ram in bytes) nonlocalVRAM=3741430784 (total vram - GPU ram in bytes) then set the cfg to read only, and now after making the changes I haven't been able to get arma2 to crash. To test it I switched it back and the crashes returned. I will do some more testing when I have time with different amounts of ram installed, and more time in game testing, but it would be worth a try for anyone having a problem with high amounts of ram. or maybe even low amounts where arma2 could think your GPU has less than its total ram.
