CPU: Intel i7-8700 RAM: 32.0GB

Just also tried switching to the latest NVIDIA Studio Driver, unfortunately doesn't seem to have had any effect either

Hmm, if I intentionally trigger the behavior, it definitely creates spikes in GPU and CPU usage... possibly also disk I/O, though I'm not sure about that. Just based on the percentages Task Manager shows me, they seem like modest spikes (<10% for GPU/CPU, ~0.1MB/s for disk I/O) though I don't know how useful a metric that is. Not sure how to tell which driver I'm using - the GeForce experience app says I have the latest driver, GeForce Game Ready Driver version 537.42, but if I go into Device Manager, it says the driver for my display adapter is version 31.0.15.3742 (it says it's provided by NVIDIA though). I tried lowering my polling rate to 125Hz, no dice unfortunately. Behavior in Affinity stays the same.

I have the latest Nvidia driver installed, yeah. My mouse is a Razer Basilisk V3 - it looks like the polling interval is set to 1000Hz.

Confirmed, same thing is happening with the setup RTX 2070 + Low quality + Hardware Acceleration disabled

Hi, I just bought Affinity Photo for Windows after trying out the demo a while ago and I'm disappointed to find out the mild stutter problem I was encountering before seems to have gotten significantly worse. For example: with my Performance settings set to: Renderer: Default (NVIDIA GeForce RTX 2070) Retina rendering: Low quality: (Fastest) Hardware Acceleration: enabled If I create a new, empty document, and just click on the Artistic Text Tool, my mouse immediately gets stuttery for a second or so (I would describe it as looking like it's only updating it's position a few times per second). Similarly, if I then type some text using the tool, and then drag it around with the Move Tool, both when I start and stop dragging, there's about a half second where both my mouse and the app itself exhibit the same stutter. It seems like doing basically anything causes this stutter. Of those three Performance settings, the only thing that seems to fix it is switching to the WARP renderer. If I use that, everything is much smoother. There is some lag & screen tearing when I edit the document which I don't get with my graphics card, BUT it doesn't affect my mouse inputs and it doesn't stop and start randomly, so it's a lot more usable. Let me know if you need more details on my graphics driver, OS, anything else.

Ahhh, my bad, I misread! Though now I'm doing more testing and even with my original settings, the issue has still gone away. So I guess it must not be consistent? I'll definitely experiment with the retina and opencl settings if it pops up again, though. (Thanks for your help, by the way!)

My inital reply seems to have disappeared? Sorry if this is a double post: - I don't see any other graphics cards in device manager - Retina Rendering was already set to Automatic (Best) - I tried changing to "Low Quality" just in case, didn't do anything though unfortunately. You did mention OpenCL though, so I tried turning off OpenCL acceleration and that actually seems to have fixed it.

Small update, I decided based on some other forum posts to try switching from the default renderer (NVIDIA GeForce RTX 2070) to WARP and it eliminates the random stutter, but now moving things around causes some weird artifacting and is generally not very smooth.

I've been using the trial to test out Affinity Photo (Affinity Photo 2.0.4 on Windows 10), and I keep encountering semi-random stutter using it - like, the framerate of the application gets really low for a second or so. I was encountering this CONSTANTLY when I was adding a bunch of shapes to a document, like almost every time I would drag anything anywhere. To test a little bit, I created a new document with just a single image layer in it and nothing else, and if I just select the image and wiggle my cursor up and down, my cursor will occasionally stutter in the same way, even though I'm not even moving the image, just my cursor. This doesn't happen if I don't have the image selected, interestingly. Overall really happy with Affinity so I'm hoping this is solvable, would love to switch over to it as my go-to photo editing software!
