Im having an issue with performance after installing an M.2 drive. Performance is limited to data on the M.2 drive and video. The M.2 drive seem to affected the graphics responsiveness along with its own performance. Specs below
BIOS - setup PCIE mode to M.2 that was the only change after installing the M.2 drive. M.2 drive is gaming files only no OS
2x Kingston 128 SSD raid1 - OS installed here
Maximus VII Hero
4790K
32gb RAM GSkill Ripjaw Z-series
M.2 - Samsung XP941
XFX R9 290x 4gb
I know M.2 uses PCIE bus but from what I was able to find googling before purchase was M.2 should NOT affect video performance. Not sure if Im missing a setting or something. When I play the game from the OS-SSD partition it runs perfect. From M.2 its garbage or cant even load
