LSFG capping onboard Intel UHD Graphics rate to 2/3?

[vlbastos]

Hello all. I'm testing a new syncing setup that involves using the onboard gpu (Intel UHD Graphics from a Core i7 11800h laptop) in LSFG instead of the main Nvidia RTX gpu. I'm configuring the display to 90hz, 120hz or 144hz, and RTSS (latest beta with reflex) is doing the frame syncing.

I'm getting wonderful results with it, but there's a weird catch: LSFG is capping the max fps to 2/3 of the refresh rate. It's like this: if the monitor is at 144hz, the max fps when LSFG is turned on is 96. At 120hz, max fps is 80 (very stable config! best so far), and at 90Hz, max fps is 60.

While running games at 80 fps onscreen using half of the render power is great for keeping my laptop cooler and such, I'd love to go all the way to the 144 fps using my onboard graphics for LSFG, but the highest I can get is 96 fps (48 fps real rendering).

Any ideas? I tested playing an old 3d game using the onboard gpu instead of the RTX, with LSFG turned off, and it was running at 144 fps without any problems (synced with 144hz monitor). I tried all the vsync options in Intel Graphics Command Center. Could it be a bug in LSFG (or Intel drivers)?

I think your UHD gpu is running behind, you might want to decrease the resolution of the game and scale so that it has less "frame" to generate. Framegen with an iGPU might not work great if the game's at a super high resolution

I already got my igpu running good here, this was a long time ago. Thanks for the input, though.
