[SOLVED] How to check if FreeSync is working when output from AMD iGPU but rendering with NVIDIA dGPU?

[DanOl98]

I have a bought an ASUS FX505DV (3750H + NVIDIA RTX 2060, 120hz screen). The 3750H has a Vega 10 iGPU.

ASUS doesn't even say it in the specs, but I've found out by installing AMD Adrenalin Panel (which ISN'T installed by default), that the display (which is connected to Vega 10) supports 48-120hz FreeSync and it can be enabled.

What I'd like to find out is whether the FreeSync works when the rendering is done by the NVIDIA RTX 2060 or not, as the communication with the display is done by the Vega 10 dGPU. What would be the best way to test it?

Windmill demo wouldn't work, as it crashes if I start it with the NVIDIA card, but it shows FreeSync actually works when starting it with the integrated AMD one.

The only way I tested it until now was by playing games without vsync (like CONTROL with RTX enabled, which goes below 60fps on the 120hz screen) and I didn't notice any artifact, but maybe it's just because it's less visible in a 120hz screen

Go in to Nvidia control panel, 3d settings, see if there is a line that says Monitor Technology. If there is click on the tab next to it and see if it says G-Sync compatible. Set it to that. Apply that setting. Then under display in Nvidia control panel see if there is a line that says Set up G-Sync. If there is click on that. Check off box that says Enable G-Sync, under that check off Enable in full window. Under that your laptop screen should be listed, check off box that says enable listed display. Under that it may say your display is not compatible but ignore that. Then apply those settings. Now test out how your display acts with the Rtx 2060 runs. Please note when in games your screen may flicker a bit when in menu etc, but in game it may stop flickering. If it flickers in all games while playing then it isn't working.

The display isn't connected to the RTX 2060. The NVIDIA card does ONLY the 3D rendering, the AMD one is connected to the display. I can't see any display in the NVIDIA panel, because I can see it ONLY in the AMD panel. And there, I can enable FreeSync.
It's almost the same as this https://www.tomshardware.com/news/use-amd-freesync-nvidia-gpu,37701.html , with the difference that I don't need a display connected to the RTX card because it's used by default (the advantage of it being a notebook).
I don't need to enable FreeSync, I've already enabled it. I just need to check if it works even when the rendering is done by the RTX.

Well you can switch from the igpu to the onboard gpu(Nvidia) in device manager. The Rtx card isn't doing anything until you do that.Then set it up like I wrote.
