The game BLUR has problems with loading stutters which i tried to eleviate with dxvk, but it seems like the stuttering is worse with dxvk. It happens mostly when there are many particles and AI cars on the screen but sometimes even in timetrials. I tried the newest version and even some of the old ones but its the same

Blur_d3d9.log

I tried a bunch of options already but nothing helps, even with async option dont help
Frametime and fps are solid at 60/16.6 but the game feels like it runs at 30 sometimes

Does putting d3d9.cachedDynamicBuffers = True into the dxvk.conf help?
If not are you able to get a apitrace of a gameplay section where the stutters occur?

already tried that option and it doesnt help. I will make an apitrace

Edit: finally got apitrace to work but with it enabled i only reach 35fps max when alot is on the screen, so i dont know how much help it will be. Also my internet sucks and the trace is 2.5 gig so it will take a while

If you are just tracing the gameplay where the issue usually occurs then the devs can check if something obvious sticks out. While making a trace then running with d3d9.cachedDynamicBuffers = True at the same time can often speed it up a bit compared to without the config.
In regards to size then you can usually end up saving a bunch by compressing the file.
