Thanks for your answer. I did some more tests and indeed, the Nvidia GPU is never used. I ran GP3 on both laptops, after setting the performance option both in nvidia drivers and in windows Display settings. (I can't disable the Intel GPU in the bios.)
To make sure I had no interference with other apps, I launched GP3 alone, without Wheeler (displays the steering wheel controls) or OBS.
The values in the resouce monitor were clear: the NVidia GPU is never used. The Intel one is, with a load around 30% on both laptops. So I guess last time, it was OBS and Wheeler which put some load on the NVidia GPU.
One weird thing with GPU Load. I set the performance (NVidia) by default, and while I could see Nvidia GPU load peaks when starting dwnd and gpxpatch, as soon as GP3 starts, if falls to 0. Meaning the game forces the intel card when it starts. The Nvidia GPU can 't be selected in GP3, I see the Intel one twice, even after making a performance test.
One other games, the NVidia GPU get a very high load immediately.
It's interesting what you say about nvidia, because I have a lot more bugs with the desktop GTX1050 than with the intel integrated. I'm wondering if Nvidia has the same drivers issue you mentionned, I should maybe try to get older drivers ?

I'd like to keep OBS, i'm recording the game and integrating Wheeler in the video to show pedals and wheel position. I'm digging through dgvoodoo and dxwnd forums to find some info, but so far not a lead on how to make both app work together... and with GP3.
