Read the error message! It says in plain text that your GPU driver is too old. I’m also not sure if frame generation is supported in Aximmetry. I expect weird results with the video plane, but please report back. 

I use the RTX4090 graphics card, and updated the latest studio driver on the official website.

But still getting an error, thanks for your reply.

Did you try the latest Game drivers? No need to use the Studio drivers.

Hi,

Aximmetry needs special versions of DLSS plugins. You can write to sales@aximmetry.com and they will give you the modified DLSS plugin.
