AffinityLover Posted September 5 Share Posted September 5 Hello Everyone, As most of you know, Affinity Photo and other products have a SERIOUS flaw and that is the lag and crash whenever you move the brushes around the canvas, regardless if you have a high end PC or not. The issue I found lies within most of the brush tools. You can use the paint brush tool and test it out. Opens your Task Manager, click on Performance tab and monitor the CPU & GPU percentage while move the brush tool around the canvas. My CPU spikes to 70% usage whenever I move the brush tools around and this happens when I selected WARP as rendering in Settings. So when I select my Nvidia RTX 3080 as rendering in Settings, moving the brush spikes my GPU to about 30% usage. This high CPU usage causes stutter and lags, even crashes on weak PCs. My CPU is AMD Ryzen 5900X, 12 cores. This is as SERIOUS performance bug that needs to be fixed! For people with mid to lower end PC, they will experience SERIOUS lags and even crashes as reported by many over the Internet. No photo editing software out there has this performance issue, except Affinity products. All the brushes that cause the SERIOUS lags due to high CPU spikes when moving the brush around is attached. You can also use HwINFO64 tool to monitor all system sensors to find performance problems. I spent hours on researching and experimenting with different settings to fix this issue. All the recommended solutions all over the Internet CANNOT fix this issue. However, I have found a way to fix this issue and put it to rest permanently! To Serif, Please find better programmer so they can help you fix this SERIOUS performance issue. Sometimes bring in new ideas and new people will help see things differently which will contribute in solving your problems. Two heads are better than one. Now to the Solution I found! I want to share this solution to the world. To fix this performance issue for good, go to Affinity Photo settings, click on User Interface tab, then uncheck "Show brush previews" and voila, your performance issue will be gone permanently. This is the only setting you need to change and you can keep all settings at default. However, you will loose that brush preview though. I don't mind loosing that since it helps getting rid of the performance lag and keep my PC running cool and quiet, and less energy use. You also needs to uncheck OpenCL acceleration if you still have problems. My system SPECS: AMD Ryzen 5900X 32 GB @3200 Mhz RAM Nvidia RTX 3080 WD SN850X 2TB SSD Enjoy!

AffinityLover Posted September 6 Author Share Posted September 6 Stevie, Have you followed my instruction to disable "Show brush preview" within the app settings? Also try to disable "OpenCL Acceleration" too. See if thst helps. The brush lags due to it using extremely high CPU whenever ypu move the brush around. This is an issue with Affinity products. No other products do that like Photoshop for example. Quote Link to comment Share on other sites More sharing options...
