Nah, beta likes 3GB video ram to run smooth. Most win8/8.1 missionaires are nvidia users with fps problems and stuttering. I'm not calling you that btw it's just noticable in the bf4 forums that there are some. I have zero problems with the beta, besides the obvious and already often mentioned optimizations for more solid fps and cpu utilization. 13.10B2 btw. I hold off with these newer betas which seems to cater the upcoming new cards. As for the rest, yeah it's a beta, likely made on windows 8, therefor managing the resources required in a better way. Especially if your hardware is below the recommended, which still is 3GB video ram and indeed windows 8/8.1. The recommended video cards are 2GB cards overall, which leads me to think they will optimize the final for these cards and give 3GB as a reference because that's what amd cards come with lately.
