[SOLVED] Nvidia performance is exactly the same as the Intel GPU
Hello,
I have a Lenovo Y540 with Integrated Intel Graphics (UHD Graphics 630) and A Dedicated Nvidia (GeForce GTX 1660 Ti Mobile)
I'm using linux-lts and nvidia-lts in addition to xf86-video-intel (i915) as drivers for the GPUs.
It's been a while since I've used the dedicated GPU, but when I ran applications or the entire X session with Nvidia, I would get a very high FPS, for example on glxspheres64, I would get FPS in the thousands, now for some reason I get almost exactly the same performance when running apps or X using Nvidia as the Intel GPU (around 140 fps on glxspheres64), I've updated the kernel, drivers and system multiple times in the past period, so I don't remember exactly which kernel/driver version was this working as expected before.
I've used the guide in Arch wiki: NVIDIA_Optimus to configure Nvidia X11 config using the file
/etc/X11/xorg.conf.d/10-nvidia-drm-outputclass.conf
and it worked fine back then and I would get a much better performance (fps) when using the Nvidia as a Primary GPU, but now even when I only select the dedicated GPU from the BIOS and run the X using Nvidia driver only I still get the same performance as the Intel card.
Below are some info about my setup:

I'd appreciate your help.
Thanks

Re: [SOLVED] Nvidia performance is exactly the same as the Intel GPU
Do you run a 144Hz output?
export vblank_mode=0
__GL_SYNC_TO_VBLANK=0

Yes, the display is actually 144Hz, When I set __GL_SYNC_TO_VBLANK=0 or vblank_mode=0 before running benchmark tools it improves the FPS even on the Intel card.
Now I understand why.
