Sluggish Performance - tech question

Hi Crew

I'm having a slow performance issue and just wanted to get advice. Have tried all the obvious things that I know of such as updated drivers, cleared the autosave folder. I'm using Lenovo pc with 16gb ram. Task manger says Affinity is using around 4663 mb. RAM is set at 47000 and undo limit is 160 - not that I need it that high. Open CLU acceleration is enabled. The personaBackstore file is 26 GB - is that ok?

Nothing else open - only Affinity. The program has been crashing frequently. My current file size I'm working on is 300dpi, 17000 x 11000 pixels and most around this size. So, within range of largest file possible, but maybe still big enough to cause crashes and slow performance? - by slow it is taking around 30seconds to a minute to carry out copying a motif to a new layer and brushes are slow to respond. I'm working in raster/Pixel so not a vector issue.

I will make my file smaller in the future, just wondering if I can fix this slow issue now? Please advise any and all suggestions. I have intermediate tech skill, not a complete newbie, have been using Affinity since its relaunch, so not overly familiar with how it runs. Probably just the file size is my issue?

Quote from Toblerone

I don’t really know what it’s for, but under “Help > Benchmark”, Affinity provides a test to assess your device’s vector and raster performance.

You have to keep in mind that 300 dpi and 17,000 × 11,000 pixels generate a very large amount of data during editing. With so little memory (16 GB) — the system and other processes also require RAM — the program will heavily write to the disk.

Does it make a difference if OpenCL acceleration is disabled?

No difference so I kept it enabled. That's my thinking - a big file. I'd love more RAM. Will make smaller files to work with. Thanks for the advice

I carried out 3x Benchmarks. Thought the data might be of interest.
