What are your experiences running different video games? I'll start.
Warframe is super laggy, even on lowest video settings, in Windows 8.1 x64 with 100GB HD, 2GB RAM / VMware Fusion 6 / Mac OS 10.9 Mavericks x64 / 13" mid-2013 Hasell Intel Core i7 MacBook Air with 300GB HD, 8GB RAM. This could be due to Warframe using DirectX 10, whereas VMware Fusion only hardware accelerates up to DirectX 9.
