Hey. Im going crazy here, i have tried everything i possible could ever think of and my head is about to explode, really. I have tried re-install Arma2 3 times now and different mods tried and vanilla dayz - same issue with all of them. I have tried alot of different servers on every mod :/ It does not matter if i have setting on lowest possible or everything on Ultra, same issue. Using MSI Afterburner and the GPU usage in-game is spiking up and down ALL the time - its fine out in forests but when i come close to houses/cities - its start spiking up and down from 1% to 50% - Every second - This is causing the lag, its not playable at all, can barely move more or less. I have tried launch options that people recommend. System specs: Intel i5 4670k @ 4.6 Ghz. Asus VI Maximus Gene. 8 GB DDR3 @ 2133 Mhz. EVGA GTX 780 SC ACX 3GB. 2x Samsung 120GB SSD. BenQ 24" 144Hz monitor. Corsair H100i CPU-cooler. Windows 8.1. No heat problem - CPU at 100% is not going above 60 degrees, even in stress-tests and it is a 100% stable overclock. Been building computers for the last 12 years and im well aware of what im doing, have really tried everything i could think of. Reinstalled every driver, tried different Nvidia drivers, old ones, new ones and beta. Same issue. Anyone with a similiar issue? Any tips? Tried every search i could imagine and found nothing similar to this. Any help is greatly appreciated!
