Laggy viewport interactions during IR using Intel GPU AI denoising

[hurrycat]

Is anyone else getting a 1-3 seconds lag everytime you try to move/rotate an object during IR, using the Intel GPU denoiser (and after 5 seconds that the denoising has kicked in) or is my GTX1650 begging to be replaced?

The same lag is close to non-existent using Nvidia GPU denoiser.

Using 3ds Max 2024 and Corona 11 HF 1.

No lag here, but i have slightly newer card - RTX3060. Intel denoiser kicks in slightly slower than Nvidia, but produces significantly better outcome. Both feels equally snappy though.

Make sure that you have "force path tracing" enabled in render setup - makes huge difference in IR responsiveness.
