Allright, the first thing I want to say is that I love Affinity photo.  It’s range of functions is extraordinary, the interface is pleasing and the results I get are fantastic.  The only complaint I had was that after a certain amount of use it began to become increasingly sluggish and performance fell off quite dramatically.  I could see it was really struggling with frequent “not responding” messages , whiting out screens et cetera.  Although I trawled the Internet to find a solution to this very irritating problem, nothing was convincing and the Affimity team did not seem to be taking it very seriously.

I think I have finally found a solution.  First of all, for all of you who are not technical geeks (like me), you should know that AP uses a lot of VRAM, the memory which is found on your graphics card.  If this memory is insufficient, performance will inevitably become poor.  My computer set up consists of an Intel i5 4 cores with an Nvidia GEFORCE with 3 GB of VRAM.  I started to monitor what was using the VRAM.  First of all, I was shocked to find that Firefox with 10 tabs open had increased VRAM usage to 70% with no other application open at all.  On my computer, the base VRAM with no programs open is 19%.  This means that Firefox was using something like half of all available VRAM all on its own!  When I completely shut down Firefox, my VRAM use fell back to 19%.  The first thing I did therefore was to jettison Firefox which is clearly a gluttonous monster when it comes to VRAM.  Other browsers are much better. Edge is now my preferred choice, taking up VRAM usage by only 5% with numerous tabs open.  But Chrome is also good.  So, if you have Firefox installed and are having performance issues with AP you may have to look no further.  My advice is to change your browser and preferably to shut your browser down completely when using AP.

I also checked on how much VRAM AP uses.  When I open AP, VRAM usage moves up to 23% from a base figure of 19%.  If I open five photos this figure increases to 47% with no other programs operating.  This is already quite a lot, and it is easy to imagine why problems arise if you have Firefox working in the background.  What seems strange however is that when you shut down the photos, although VRAM use falls it does not go back to the original figure, seemingly holding on to memory it does not need.  Why this occurs I have no idea. Perhaps AP engineers can offer an explanation.

So the second thing I did was to experiment with using the WARP “preference” which can be found in the preferences tab within Edit.  This is an alternative to relying on your own graphics card. Using WARP with no other programs open, AP with five photos open uses only 31% of VRAM, a much more reasonable number.  I have found absolutely no difference in performance (speed etc.) when using WARP. AP behaves as it should.

To summarise, if you are having performance issues, I recommend that imperatively you change your browser from Firefox if you use it and/or shut down your browser when using AP.  Secondly, turn on the WARP preference.  Also, limit the number of photos you have open at any one time to a maximum of around 5.  Regularly save your photos and exit from them.

I hope that the above is of some use to fellow sufferers.

Pretty much reflects my experience  I currently have 10 images open, which is a fairly normal number for me, but that seems to be my machines limit for now.  That being said, when I watch my CPU usage and frequently find it pegged at 100% and memory nearly pegged as well.  I'm currently shopping for a more powerful CPU with as much ram as possible, the current machine is an i7 with a 2 core processor and 16 GB of ram and a SSD drive.

Hi @NigelDuke and @PeteThailand, thanks for the posts. We've done a lot of work in the 1.7 betas to improve performance, so I'm hoping that you will see a lot of benefit from the next patch. If you can't wait, feel free to grab the installer from the beta forum and give it a try (note the caveats about using the beta for production purposes in the pinned post).

Further to Mark Ingram's helpful replies, I downloaded the 1.7 beta version. My initial impression is highly favorable. I opened 5 files in AP (no other apps open) and VRAM use rose to 37% but then fell back to 22% when I closed them. It seems to work comfortably with Vivaldi browser on and as suggested I can keep the renderer on the graphics card. Not seen any annoying "not responding" messages either. Will keep the forum posted after a longer test period. But so far I can say hats off to the developers.

Definite improvement, in loading a 25MB file this morning it looks like a 7 second improvement over the 22 seconds on 1.6.5.135 on my I7-7500 2.7Ghz machine.

Since I've been using the Beta I have been taking advantage of  using both versions, when the primary version bogs down with processing, I use my time to move

over to Beta to work on a second photo, so it saves me quite a bit of time using that methodology.  My question becomes... is there a way in which I can have multiple copies of AP in one machine?  Either by buying additional copies, or any other method?

Observations on the latest Firefox update.   Surprise, surprise  the latest update of Firefox has taken it from a major consumer of CPU and memory (at times, under certain conditions over 50% of the computers assets)  to insignificant 0-5% of memory maxing at 20 or so % and less than 25% of memory instead of 40-60% !!   With the latest update of AP beta the loading and developing have had a very significant increase in performance.   I'm still looking at a faster computer,  be it with less urgency than earlier this week.
