Significant perf issues with all three apps - Windows 10

Recommended Posts

I'm seeing serious perf issues when working with complex files (lots of pages, layers, etc.)

For instance, I'm making adjustments to this vector image - a series of 26 straight paths from a center point, with four circle paths. There's also a number of hidden layers in this particular project.


When I'm actively working in Publisher and Designer on this project, perf is just terrible:


This machine should be able to handle things just fine - I have a 4GHz i7 6700K, 48GB RAM, and a GTX 1080 with 8GB VRAM. This machine generally doesn't have performance problems this bad in other demanding applications (like Adobe's stuff, Office, Visual Studio, etc.) I have hardware acceleration enabled.

It's not causing perf problems to the point that the software is unusable, but it does mean there's a noticeable lag between clicks and responses to clicks.

I seem to have far fewer problems with the same version ( running on my laptop, which is an AMD Ryzen 7 PRO 4750U with 32GB RAM and AMD Radeon GPU, so it might be something going on with my local machine, but I'm unsure what to look at first.

Hi @ClairelyClaire,

Sorry to hear you're having trouble!

Firstly, can you please navigate to Edit > Preferences > Performance  in the Affinity apps and provide a screenshot of your settings here for me?

Secondly, slow performance can sometimes be caused by outdated/corrupted GPU drivers - so I recommend installing the latest available driver as a 'clean install' to see if this helps.

Can you please visit the following link and download the latest drivers available for your system - 


Note: you may need to go direct to your PC manufactures website for the driver, if you see a warning regarding 'OEM drivers' when trying to install one from the above site.

Once downloaded, please do not install the driver yet.

Now, download DDU (Display Driver Uninstaller) from the following link, this will remove all previous drivers from your system -


With DDU downloaded, run this to remove your current drivers. Once these are removed, install the drivers that you have in your downloads folder from earlier.
Once the new drivers are installed, restart your system and then re-launch Affinity.

Do you see better performance now please? :)

Thanks for the tips. I haven't had a chance to do all the clean driver remove/install stuff, but I disabled hardware acceleration to see what might change, and I definitely think you're on the right track - perf is noticeably better without HW acceleration enabled. That's a pretty good sign it's a driver issue. :)

So I will get to the GPU stuff as soon as I have the time!!
