Things turn better after using the old nvidia driver from March 2018. Output on 3 Screen, content on comp size. im now able to run at about 30FPS, which is all i need!

now im on the next task for 7680x5400 with 7 output, is that even possible on 1080TI machine to run smooth at 30FPS?

Content is on DXV3 format same as the comp size. and 4K also.

comp size 7680x2920, got only 20FPS when 3 x 4K output enable.

3 x 4K output + 2K GUI
