GTA IV 1.0.4.0 long load times issue

[Omarock92]

Please describe your issue as accurately as possible.

My load times more than quadrupled in IV 1.0.4.0, (don't have this issue on patch 1.0.8.0). I'm on Win 10.
Tried previous DXVK version (2.3.1) that I'm 100% positive it was working fine before, but still exhibits the same issue.
I feel like this might be caused by a recent Windows or a GPU driver update.
Any help is appreciated. Thanks!

Please make the apitrace that the issue template asks for. You can find a guide here: https://github.com/doitsujin/dxvk/wiki/Using-Apitrace

I don't have access to old builds of the game so I do need that Apitrace to take a look.

How is this compared to without dxvk?

Note that at least in some instances with this game loading dependent is on fps, such as when using the -managed option #2982 (comment). I don't know how the behavior is with older versions of the game.

Edit: I see you have a fps limit set for dxvk. Does it improved if you remove it?

I tried this but the game wouldn't launch at all with Apitrace DLLs.

Edit: Nevermind, was able to launch it after unticking "disable fullscreen optimizations" but couldn't reproduce the issue because it's launching in DX9.

Without DXVK the loading times are fine, removing the fps cap helps but still not as fast as without DXVK.

I have been unable to reproduce this so far. There isn't much difference when i time the loading both on amd and Intel.

A thing to try would be inserting d3d9.cachedDynamicBuffers = True in to the dxvk.conf file

Strange, I've tried d3d9.cachedDynamicBuffers = True but didn't made a difference. Btw, game loads almost instantly without DXVK, even with the same 75fps cap via RTSS.
Seems like load times become tied to framerates only with DXVK. I also tried capping fps with RTSS when using DXVK and that has the same negative effect on load time.

Edit: for clarification by "load" I mean the black loading screen when the game is loading the map.
