Jean Luc, I still am experiencing a loss of 10 FPS when the 750 is on, compared to when it is off.

Here are the 2 RXPGTN logs:

17/06/17 20:56:15.600 09468 -    ] # win.xpl version 2.4.0.0

17/06/17 20:56:20.200 09468 -    ] # rxpGtnSim64.dll version 2.4.0.0

Thanks,   Howard
 

Howard, I think I've mentioned it before, but your log files show v2.4.0.0.

Please make sure to install v2.4.6.0 posted here:

 

Hi Jean-Luc.  I thought I had v2.4.6 installed, but I didn't.  I reinstalled it and that solved the problem.

Thanks,  Howard

I started using the GTN750 under X-Plane 11.02, but I found that the impact on the frame rate is obvious. After each turn on, the CPU load is significantly increased. Do not open the GTN750 can keep 30 frames, open the GTN750 only 20 frames. I do not know how to fix this problem.
My computer configuration is as follows:
CPU I7-3770K OC4.5Ghz
Memory 16GB
Video card NV 1070 8GB
Hard disk SSD512GB (SATA3.0)
Display resolution 2560 * 1080
Operating system windows7-64

 

Hi, have you tried the latest v2.4.6.0 posted in at the top of this forum? 

It is in preview for now, and I'll make it the official release today or tomorrow.

Hi, I have installed V2.4.6 version, now frame rate back to normal, very grateful!
