Variable 322 Posted December 10, 2009 (edited) Just managed to overcome crashing to desktop I experienced ever since I installed the game, maybe this will help some of you guys. Before I got the fix it, I tried disabling PhysX but it didn't help. When I looked for some more GFX settings on the Nvidia control panel I stumbled upon this (note the bottom part): It's rather dissapointing to find out that GTX275 compatability to ArmA2 is only "Fair", and nothing is mentioned there about preventing CTD's, but I tried to do as reccomended there and disabled the "Advanced Shadow Detail" and lowered the "Post Process effect" to Low (In-game advanced video settings). The result was no crashes at all! Well, the game doesn't look as good as it was before but at least I didn't have a single crash since :bounce3: This is my complete spec list: Intel® Core™ i7 Processor i7-950 + Motherboard DX58SO 3x2GB Corsair XMS3 Triple Channel WD 1TB IntelliPower, 32MB, SATA II WD10EADS Asus GTX 275 896MB GDDR3 DX10 HDTV 2xDVI PCI-E One more tip: During my crashing period I also had wierd graphical artifacts sometimes. That caused me to suspected the GFX card rather high temperatures (it used to get up to 75+ degrees Celcius). I managed to fix that using Rivatuner tweaking software and following this excellent . It didn't solve the CTD's but it lowered the card's max temperature to only 65 degrees! Highly reccomended.

kklownboy 43 Posted December 10, 2009 a 275 is a mid range card (relative to 285,295,4890,5850,5870,5970). Whats the rest of your system? CPU MB ect... Share this post Link to post Share on other sites

Maybe, IN YOUR OPINION... facts indicate something different... if a 275 is a mid range card then so isn't a 285. in some benchmarks the 275s come out better than the 4890... http://www.techpowerup.com/reviews/Powercolor/HD_4890/6.html :lecture: Edited December 10, 2009 by [DirTyDeeDs]-Ziggy- Share this post Link to post Share on other sites

kklownboy 43 Posted December 10, 2009 -Ziggy-;1511796']if a 275 is a mid range card then so isn't a 285. they are practically identical and in some benchmarks the 275s come out the better.:lecture: Not in this game. A 275 is a maxed out 260' date=' you can check the specs, and its a nice card. You have two of then in a 295. Semantics i call it mid, but others would call it mid/high... whatever, But A2 wants more card for max settings at HD res...maybe thats why he gets "Fair". But what is the metric that prog is using, i know for my res and IQ settings a 275 would be to slow by its self. But as to the CTD, it maybe a a system issue other than his card/drivers, more info needed. Updated my original post.try turning off HT in the bios Share this post Link to post Share on other sites
Variable 322 Posted December 10, 2009 try turning off HT in the bios Ok, trying that now. Could you please explain some more about your reccomendation? Share this post Link to post Share on other sites
Avoidable 10 Posted December 10, 2009 Correct me if I'm wrong but isn't the steroscopic 3d compatability purely something to do with the 3d glasses and nvidia 3d vision thing? I don't think this is refelctive of performance when using arma normally. Do you use the 3d glasses? If so then disregard what I said. At any rate, I'd be checking a few different drivers out to test compatability with your rig and arma. I get random ctd's too, but I think its an SLI issue Share this post Link to post Share on other sites

Played about 3 hours with all graphics maxed out and didn't experience even one crash, I also think that Arma2 runs much more smoothly now. Thanks a lot. Do you think disabling hyper threading can cause any issues or lack of performance in other games or outside Arma2?

S-M 10 Posted December 11, 2009 I run a GTX275 on my quad and while i can only run a 1024x768 screen res due to this monitor, i can run a 200% screen render res with no apparent ill effects (maybe 1-2fps drop), especially on the latest beta patches. Disabling physx did nothing for me when i was testing stuff out to be honest! Glad you sorted your machine out :D Share this post Link to post Share on other sites
Bulldogs 10 Posted December 11, 2009 Yup, that "Fair" rating is a rating for Stereoscopic 3d with Arma 2, not the normal GTX275 rating.. Unless you're actually using 3D glasses with a CRT monitor on Stereoscopic setup then I'd suggest disabling anything related to stereoscopic 3D. Share this post Link to post Share on other sites
