DoGy

I would upgrade the RAM to 8GB, because 4GB is in my eyes not enough. When I work with programms on my PC, sometimes I have only about 2GB free from 8. There are also many games that benefit from it too...

My specs: Windows 8 Pro 64bit i5-2500K @4,2Ghz Sapphire HD 7950 OC @950mhz 8GB DDR3-1600-CL9 Infantry Showcase FPS & Usage 2560x1440 (Native is 1920x1080) 4xAA ATOC no FXAA/SMAA Post Process: Normal (everything higher are minimal changes in optics, but need a lot of FPS 5-10) This settings doesn't hurt my FPS. HDR: Standard AF: Ultra PIP: Ultra Dynamic Lights: Ultra Sightrange Visual: 1500m (Higher would need more object view, but that will kill my FPS) Sightrange Objects: 1000m (This one kills your FPS) Sightrange Shadows:100m (No noticable changes in FPS, find your sweetspot with your shadowdetails higher range=more blur) Quality Texture: Ultra (This should be no problem for GPUs with 2-3GB VRAM) Object: High (This need also much performance) Terrain: High (Sighrange of gras etc, high is a good balance) Cloud: Ultra (no FPS change for me) Shadow: High (Ultra does cost only 2-5 FPS more, but minimal change) !!!But LOW shadows need more than Ultra this is since Arma 1 for me :j: Particles: High (no visual change on Very High, maybe sighrange, but it need more) With this setting I get 70-30FPS in the infantry showcase. GPU Usage 99% with CPU limit it goes down to 50% VRAM Used 2,5GB CPU Usage 40-80% Same settings without Downsampling "only" at 1920x1080 FPS are 80-38 VRAM about 2,2GB I would bet some 2GB GPUs could get problems... Performance killers are smoke (2 smokegrandes cost me 10 FPS), AI, many vehicles (physics)
