I cancelled my Steam Aces High account because Steam makes HiTech use the DX11 version. Now that im back to paying HiTech directly, I still use DX11 because DX9 has really long alt-tab load times for me. I prefer the stutter everytime im about to drop a bomb or shoot someone since I alt-tab alot in downtime. Would be nice if it was addressed instead of passing it off as Microsoft's problem.
