Anyone who plays Arma 3 and gets 60 fps on ultra in Altis? I always get arround 40 never 60. help plox
My specs are GTX 660; 8GB ram/3.5ghz i7 quad core win8 64
I haven't clocked my rig on ARMA 3 on Altis - but I run solid FPS.
I run an AMD card and CPU - an 8350 (8 physical cores) clocked at 4 GHz, 32GB RAM (forget my clock settings on that - 1.6 GHz if I remember correctly with CAS latencies in the 20s if I remember correctly - but I haven't done nearly as much tweaking on this rig as I did with my A64-3700 Socket 939 back in the day). The Graphics are an AMD 9770 - 4 gigs with the DAC at 400 MHz (which steps up to around 1.6 GHz on the multiplier, if I remember correctly).
I'm running Windows 7 - so that is another difference.
ARMA 3 is a simulator - it's going to be -very- CPU intensive. It also uses PhysX. Nvidia GPUs rely on the CUDA architecture which is not all that well designed for parallel data execution. Nvidia went with a "Fast and deep" approach to the execution of CUDA. PhysX can run on graphics cards well, and can also be run on CPUs well. It cannot be run across both very efficiently.
The PhysX operations will likely be crowding out the graphics processing resources of your card or bottlenecking your CPU.
On my system, PhysX runs on the CPU and the CPU only, and I've got an extra four cores for my system to juggle parallel operations across. Which leaves my graphics card free to just do graphics.
Generally, when ARMA 3 slows down for me, it's when I'm calling in a salvo of 250 artillery missiles in from a cluster-**** of MLRSs. Or when I have two AI armor battalions engage each other. That will slam my system to a crawl (though there is more than enough computing power in my rig to handle it - much of ARMA's code is still classic and not properly optimized for massively parallel environments and innovations like OpenCL).
