Hi guys, my name's Devan. Now my backdrop is every time I've ever tried playing DayZ, my computer can barely run it (using my family's desktop. Old as shit Windows XP with a 1TB hard drive, unknown processor). Even when allllll settings are on very low and the extras (shadow detail, trees, etc.) are off, and I'm on the server I receive the best ping on, I never average anymore than 15fps. So naturally, I googled the problem, and stumbled across this thread. Following the instructions, everything was going smoothly until I got to the notepad (.cfg) and tried to change my line16 to the instructed "GPU_MaxFramesAhead=1; (Mouse Smoothing - off)", but after I did this, every time I'd try to run DayZ through DayZ Commander, I'd get an error message saying something along the lines of "[file destination] line16 '.': '(' instead of '='". I tried changing around the ine a little bit but never got rid of the mssage so I deleted the "(Mouse Smoothing - off)" part all together. Also, in the NVIDIA Control Panel, I couldn't find DayZ in the drop down menu, only Adobe, Java, and Steam, so I applied the settings to all three. Then after that, I could not find an "Ambient Occlusion" option in both global and program/file settings, so I skipped it. Besides that, I followed everything it told me to in NVIDIA, the ArmA2OA .cfg, and even in game I adjusted my settings to what it shows in the provided picture (with the exceptions to fit my computer) and I started running even LESS fps. So I started messing round, seeing what could do to make my fps better, but no matter what I put my settings to, and after all these changes, I never received more than 6fps unless I put all the (in game) settings back to what they were before. Can someone help me out here, is this only happening because of what I "modified" in the process or is it because of my shitty computer all together? Any help is appreciated, thank you
