optimization [SOLVED] Progressive increase of frame time for no reason

[len4ikuz]

After starting the world as build frame time slowly increasing causing fps drop from 140 to 60 and even 30. Microprofiler info doesn't show a thing that could cause that. The only thing it shows that every render aspect just takes more time every frame e.g. render of opacity object at 1 frame took 1.5ms and 1.95ms at 490.

There's no issue with fps in editor.

PC specs:
- Xeon2689v2
- 32gb DDR3 RAM

- RX5700XT

Latest microprofiler info added.

Hello!

This happens only with DX12? Can you test DX11 / VK behavior as well?

Thanks!

Yes, it does happen. I provide microprofile files. Vulkan starts with better performance but ends up lagging, DX11 slower by itself but there's still visible difference between profiler start and end.

Could you please also inform us if this issue only occurs in your current scene or if it can also be observed in a newly created empty template scene?

In case that is only related to your current scene, we would need access to it to reproduce the same behavior on our side.

Could you please check and send us the scene if that's required? You can upload it to any file hosting or our FTP server.

Thanks!

It does happen with completely new scene too. I've sent google drive link to the s1lent's DMs in Discord. FTP thing isn't the easiest to work with)

As far as I understand the issue is probably related to the specific GPU. Enabling vsync reduces GPU load and framerate became more stable without noticeable drops.
