You are right, in complex scenes(for example"CannelleEtFromage") , my gtx 960 lags very much(or crash), however, we can always switch to the cpu render in viewport,it may be slow, but very usable.
I really like this "effect of neural networks",as if someone is painting on viewport

And here's my test, with a rather simple scene and an RTX 2070.

Works really well and super useful. Only the frequent crashes are a bit problematic right now. Maybe you can make it opt-in (like CUDA/optix in the addon preferences) until it is fixed? Or is there such a possibility already?

You can change the viewport denoiser back to OIDN in the render properties, viewport panel.
The crashes need to be fixed at the root. Towards this purpose, it's actually good to put known unstable features as defaults to get as much data on the problem as possible. v2.5 is in unstable alpha testing phase after all, which is meant for testers, not end-users and production.

Right, thanks! I only saw the final render setings.

Agreed, I just wanted the option.

I've downloaded latest alpha version and it shows me after compiling kernel_cache in the viewport "OptixDenoiserPlugin used while Optix is not available".

specs: Win7 x64, v2.90 alpha, v441.87 driver

Looks to me like your driver is too old. You'll need 450+.
Also not sure about Win 7, could be that OptiX doesn't support it.
Blender 2.9 is not supported by our addon, you might want to test with 2.83.

Ok. I will look into it. Thanks for the inform
