I have a problem and after 24 hours of research, I am always at the same point so I seek your help. Okay, let's be clear. My GPU score in 3D11, Fire Strike, ... is really not good while on the Z270, it is correct. For the 3D11 benchmark latest version 1.0.132.0 Z270 APEX + 7700K 5GHz + 1080Ti 2050/1500 + 16GB 3600C15 -> P28425 (43708 - 13664 - 14199) X299 DARK + 7980XE 4.5GHz + 1080Ti 2050/1500 + 32GB 4000C19 -> P33211 (41229 - 22291 - 18948) I made several installation (win10 1703 on both motherboards), same Nvidia drivers, same benchmark, I have tested with win10 1709... I installed the APEX X299 and bad GPU score too ... For me it does not come from a hardware component, nor the nvidia drivers, nor the benchmark, ...
If you have an idea... thanks !
