Or check out the written guide on the LS Discord:

And the "Secondary GPU Max LSFG Capability Chart", the numbers you see there are the max possible total fps with x2 framegen and 100% resolution scale/flow scale.

Awesome!! Thank you for sharing :)

When playing modern titles, dual-gpu is where LS shines best.

I set my system up to take advantage of this last week.

岂不是可以用核显进行帧生成了？再往后面甚至可以专门出个帧生成硬件卡？期待

Can't access the discord through the link. Or at least, it doesn't load the channel's content--just stays blank. Anyone else had this issue?

You need to be logged in to Discord.

I can say the same thing as King Thrawn. And I am logged in.

Edit : You need to register into his discord channel from the lossless scaling app, then you can use the link.

I have the amd Ryzen 7 3 9800x3d , can u ise the APU to generate frames for LLS?

Yes. Try it and see how well it works for you.

Do I have to connect monitor to the 2nd GPU for dual-GPU setup? while setting the main GPU as the GPU reference in windows graphic settings?

the secondary gpu does not need to be be connected to the monitor output, though you can choose to use it if you need to.

I've tried LS on 2nd GPU 1660S and it does help a bit when framegen X4 but the base framerate still decreased by 5 to 7fps, ngl it's better than on main GPU which decreased by 10fps+, but is it worth it? imo not really worth it because it adds 45 more watts on the second GPU and more heat generated inside the case.
edit: actually worth it when upscale to 4K and framegen x4, I just need to open the case for better air circulation.

I tried it with two 3080s and it works. However, the latency increases drastically if the GPU 2, which calculates the real images, also increases the latency above 90% load. However, it is clear that you can gain 10-20 FPS real images with it. But the high load on the GPU still gives the high latency, this is not the fault of LSFG but in general.

Will this work with external GPU (Nvidia for example) and GPU that is built-in into CPU? That way we can use extra GPU for extra frame generation.

edit: it reminds me (just a bit) of old technology from Lucid Virtu MVP. There was a mode called Virtual V-Sync & HyperFormance - it claimed to reduce input lag and improve frame pacing by combining GPU workloads (though results were mixed). The technology is now abandoned and some of solutions are being used in Nvidia Optimus (switching GPU's to save power when needed - but not combining the two different GPU's power)

yes but the iGPU has to be powerful enough to run LSFG, something minimally in the ballpark of iris xe or 680M
