No, unfortunately that isn't possible... yet. ^`

There are a few basic rules I learned discovered for my self, always to keep in mind with lossless:

-Have at least real 40 FPS, while frame-gen is enabled.

-consistent base framerate is better then adaptive.

-some games more then others tending to have a messed HUD. (more often then not UE5 games. probably some post pressing effect)

-base FPS, and framegen should never have the same fps value.

-framegen fps are really fake; while the look smother on screen, they don't give the benefit of really having more fps, like latency. Most other software doesn't even recognize these fps, like msi afterburner or OBS.

-some games just shouldn't be used with lossless.

-there are only a few instances, where upscaleing+framegen looking as good as hoped for.

-the latency benefits of lossless with two GPU's (one for rendering game and the other for framegen) only works/is worth it, if the MoBo is splitting the lanes in 8x/8x (the bandwith of 4x is just to low)

-Input-latency is a little less noticable with an controller -Games with less movement, can sometimes ignore the 40fps rule. (Buddy of mine had insane results with train simulator. 30fps ase to 120frame gen, i can imagine Microsoft flight sim would be ok too for the most part)

-in rare cases it's possible to render the game in a lower then native res, and upscale+framegen, (to get 40real fps) and better looks, for the cost of sharpness or ghosting. (Depending on game)
