I honestly think there might be something to this idea, as I've considered it in the past. The way the lags feels no different than before I upgraded my GPU from an HD6850 to the current GTX670 and reformatted, though I do get better video performance overall. When I started the game up for the FIRST time it was completely lagless, but as soon as I hit Cherno everything went downhill from there and it has never been the same since. I'll take me a little while to set this up, but I'm gonna try it today. Thanks. Whoa, lol, that sounds like an awful bug man. Clipping head hahaha. I've recently used my DataVac to blast the shit out of the inside of my comp, but I'll check again in case something has gotten clogged. I've run other games with much better performance, like Portal 2, L4D2, Metro 2033, etc. Tried default, high, very high, none of it seemed to make any difference in performance. It won't let me change priority in Win7, just says access denied. Thanks. I actually started the game out on very high, I've been messing with them all and none of them seem to do it. I'll keep fiddling but I don't think it's making any difference. My FPS seems to stay the same within 10 FPS regardless of the settings, it's just choppy as hell. Thanks man. I was banking on the standalone. My FPS is anywhere from mid 30s to 40s when looking at dense parts of Electro, it goes up to 50, 60, and even above 90 inside of buildings, etc. Out in the forest it's a constant 50fps+. I'm perfectly happy with this, I just can't fathom why it's not smooth, even when it's at 60 fps. This is why I think there must be something I can do - your processor is better, but my i5 2500k isn't even hitting max usage, and I have the same video card. Hard to say, I've been on 10-15 since my reformat and every single one has had this issue. Thanks for the response. Should I get the Arma2OA beta patch? I just have Arma2OA updated via DayZ Commander. I tried your settings to the letter and it did not help. Thanks. I'll keep trying different servers during my testing to ensure that this is not the issue, but I've played on so many with the same characteristic lag that I think it's something to do with my setup. Thanks. I appreciate the number of responses I got! I still have the ramdisk thing to try, so I'll probably head into that next.
