cancel rendering
Is there any way to speed up the render cancellation? In cycles, when esc is pressed instantly, rendering is stopped, in Luxcore it is still calculating for a long period.

Please upload a simplified testscene that shows the problem.

Re: cancel rendering
I found Luxcore to react way faster when canceling renderings than Cycles does - especially when also using the CPU in Cycles.

Re: cancel rendering
There is no specific scene, using only CPU I can cancel the render quickly, using GPU + CPU the cancellation takes time.
This also occurs when it is only GPU, so I believe it is the problem.

Re: cancel rendering
If it happens in any scene, it should be easy to upload one, right?

Re: cancel rendering
Hello friends, as it is happening in all the scenes I am testing if it cannot be something here in my system, I use a GTX 980 and an Intel 8700 with 32GB of RAM. I'll try to find out, if not, I'll post a test scene for you. Sorry if I was overwhelmed with the creation of the topic, but I thought someone else might be having it and comment, but apparently it is only here.
Re: cancel rendering
I know what you're talking about. Or at least, I used to...
I remember the GPU rendering used to take a few seconds to stop the 'batch' that it was working on (I think it even used to print a message like, "Waiting for render threads to terminate" or some such). The last time I noticed was a while ago, possibly before 2.5...?
I believe this is also what prompted YouTuber djtutorials recently to incorrectly instruct his audience (timestamp 29:28) that "you kinda have to spam hitting Esc" (paraphrasing). Although, you can see in the video that Blender doesn't respond and stop immediately.
However, in the 2.5 beta 1, I can't reproduce this behaviour. I think it might've been significantly improved recently

Re: cancel rendering
Would it maybe be possible to add an option like "Skip denoising after cancellation" to the Denoiser section? I render very large images and every time I cancel a rendering I have to wait for minutes until the denoising finished (which I don't need). Sometimes the PC won't respond at all and I have to force-close Blender.
That would be great.

Re: cancel rendering
I fully support this proposal.
I also find myself in stupid situations where I have to cancel the rendering, and I can not wait for the OIDN - click on xkill
