So I have been unable to get hardware acceleration on my iGPU correctly, I have a dedicated Nvidia card which I can confirm works, but when I try to run video on my iGPU, it can’t display framerates above 30 without extreme stutter. I tried manually setting up my xorg.conf file without any luck, after doing so, I either get xorg crashes or boot into my Nvidia card. I also tried declaring which drivers to use as environment variables, specifically following what is said on Hardware video acceleration - ArchWiki and configuring driver names. I have all relevant drivers installed and have tried both declaring and removing VDPAU_DRIVER variables. VAAPI is listed as working but web browsers seem to default to VDPAU.
inxi -G output with GPU active

and if I have the iGPU running, xrandr --listproviders gives

and if on iGPU
When I try to use xrandr --setprovideroffloadsink 1 0 I get
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 34 (RRSetProviderOffloadSink)
Value in failed request: 0x1e9
Serial number of failed request: 16

Regardless if I’m on my Nvidia or Intel already.
Using this command doesn’t seem to change anything
xrandr --setprovideroutputsource Intel NVIDIA-0
And if I run it on the iGPU and swap the outputsources I get
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 140 (RANDR)
Minor opcode of failed request: 35 (RRSetProviderOutputSource)

If I’m booted into the Nvidia card, vdpau info gives

I’m skipping some of the output since you can see the main thing there, but whatever I do, I can’t get Youtube or other streaming services to play smoothly unless I’m using my dedicated GPU but I don’t want it running constantly and killing battery. Any idea what I’m doing wrong here?
Edit: Found that after running xrandr --setprovideroutputsource 1 0 while on iGPU will cause it to render with the Nvidia card for some applications (like glmark2), but it won’t decode video or render my web browser. glmark2 lists the wrong card running too but only when booted with iGPU (ie intel says it’s nvidia, nvidia says its intel). If I run xrandr --setprovideroutputsource 0 1 I get a similar error to running --setprovideroffloadsink
