[Warcraft III] Low FPS on heavy maps without cachedDynamicBuffers

[hideki2k02]

Hello, i've been trying to diagnose some issues with Warcraft 3 and i was advised to post my findings in here. Some images are also below.

My game stutters a lot at 15 FPS whilst playing heavier maps. The problem is mitigated a lot when enabling d3d9.cachedDynamicBuffers

Without cachedDynamicBuffers:

Thank you for the report. I will attempt to verify this on my own rig soon ish.
Can you give an example name of a heavy map where this occurs?

Edit: nvm i just noticed the map name is in the top right of the screenshots

I got around to testing this now on my RX 7900xtx and x7950 setup with and without rebar. Trying the same Warcraft 3 version i do see that the fps is quite bad with that map (i think likely it is just the map itselft) but i cannot reproduce that the config have any affect on it,

most probably it seems to be the shader cache having an issue with rendering the game itself can you clear the shader cache if possible and retry the setup?

It is very unlikely that the shader cache impact performance.
