I tested some more tonight... it seems that the CPU spiking happens worst with vector shapes and the pen tool. Using paint brush in both Draw and Pixel persona don't seem to exacerbate the issue too bad, same with the pencil tool. However, if I try to use the pen tool.... even starting a line and hovering my Surface Pro Pen above the screen results in the CPU climbing to unreasonable levels +30%. I really need help figuring out why this is happening. I've been monitoring process and it is isolated to Affinity Designer.

What pen are you using? I assume its for a Wacom tablet and not the surface?

Hey Dan, High Precision Tablet Input is set to off.

Hey Dan, I will check the preferences and let you know. As to other drawing apps... let's be honest, are there really any other drawing apps . Yes, I have and do not register the spike (Autodesk SB and MS Sketchable). Oh, and the Beta interface and functionality is on-point. It looks and feels amazing. Alex

Okay, so I did a quick screen recording with three input methods. Mouse, finger, and pen. I did the test before and after installing the Beta and am attaching the recordings. You can see the spike in CPU/GPU when using touch input with either finger or pen. Any ideas would be greatly appreciated. Maybe i'm reading into it too much, but it seems to be an unusually high CPU/GPU load for such a menial task. Even more so to see such a variance from an input "device".

Hey Dan, I appreciate the response. I am using my surface in desktop mode. I'll download the Beta tonight and see if that helps at all. One thing to note though I don't think it would make a difference is the version of AD I have was purchased from the Microsoft Store. Not sure if the fact that would play any role into the issue... given the price v utility of AD I'd happily shell out another $50 to download the Serif store version if I thought that would remedy the issue. I'll post an update to the thread after testing following the Beta install. Thanks, Alex

Hello, I searched prior posts but didn't see anything similar to my question / issue and apologize if a Forum Guru is about to point me to a pre-existing thread. When working in Affinity Designer on the Surface Pro (specs below) I experience significant CPU spikes when working with the Surface Pen. For example, if I create a square shape and use the track-pad or any Bluetooth mouse to resize the shape I see very little change to the amount of CPU required to perform the tast. Similarly, if I resize the shape using my finger via touchscreen... very little CPU require. However, if I perform the same task using the Surface Pen (both when connected via BT and not) the CPU spikes and runs close to 100%. I confirmed that it's Affinity Designer that is requiring the CPU and not a Microsoft process / pen tool feature. Has anyone else experienced this? I'm worried about overheating due to utilizing the Surface Pen in AD. Computer Specs: Surface Pro 6th Gen SSD 512MB 16GB RAM i7-8650U Intel UHD Graphics 620
