Since Kemical's comments about the DX 12 situation, I have been doing some checking. I realized Borderlands 2 is playing as DX 9 and 32 bit, which is its normal configuration. But I downloaded Borderlands Pre-Sequel which is a DX 10 version and it is still playing in DX 9 (32 bit). I also notice when I install a Steam game, it configures C++ 2005, as do other utilities. I have not yet checked the new DX 11 game in Windows 10, but after Windows 10 is released and the content providers update, will older C++ still need to be configured? Will DX 10 or DX 11 games still run in DX 9? I checked Kemical's game in Windows 8.1 and it appears to be using multiple cores. Even the new Borderlands game locks up after a few minutes and requires a restart. I might try the Dying Light game later, but so far, not very impressed with it.
