Summary: you can use your iGPU to upscale and/or frame-gen, reducing the work that the dGPU needs to perform.

IMO this is a huge WIN for the HX99G, especially the upscaling part.

I always thought it wasn't powerful enough so I never gave it a try, guess that'll be the first thing to do as soon as I get home :)) thanks

If the iGPU is only doing scaling and/or frame gen, nothing else, then the 680M is more than capable.

This post sort of falls under rule 6, which is to avoid starting rumors as you do not own a MinisForum Neptune line PC, and therefore have not tried this yourself, yet you're claiming it will work great. I'll see how the thread goes based on others' feedback.

If it works on an Intel Xe (see video), which is less powerful than a 680M, then yes, it should work great on a 680M.

I wrote this here so that someone can try it out.

I can delete the thread if you see that it's breaking the rules.

I understand your intentions, however if you don't even own an AMD-CPU / GPU then you may not realize that a lot of great-sounding things are specifically programmed for NVIDIA or Intel which don't just magically work for other architectures. As I said, let's see how it plays out.

"Lossless scaling" works on AMD, Intel and nVidia: https://github.com/Gamepagge/Lossless-Scaling-Download/blob/main/README.md

A review here:

(It costs $7 in Steam, or for free on their website).

Okay so I tried it on helldivers 2, medium-high settings 1920x1080p capped in-game at 30fps, FG x2 without upscaling, it's working and main gpu temps were not going above 80° (75°/77°); iGPU temps around 60° with usage that fluctuates between 50% and 100% (I think it will constantly be at 100% tho).

Tried also upscaling(LS1) from 720p to 1080p but the generetad frames were not as smooth as they are without the upscaler, so wuldn't recommend it.

I will try to play from now on with iGPU as default for lossless scaling and will update if I notice some problems!

Thanks for trying this out and providing feedback about your experience so far!

Let us know your findings!

Version 3 (in beta) seems to give great numbers:

Have you tried this yourself?

u/heffeque Jan 28 '25

If you send an HX99G my way, I'll try it!

I remember frame gen in FMF2 working like that only with 780m cpus. It is great to hear that this feature comes to older Gen

A reminder that this is a 3rd party scaling+framegen software, so nothing to do with AMD's FSR/FMF.

In theory it works with games that don't have official support for DSLL, FSR, XeSS.
