[Bug 38166] Heroes of Might and Magic V performance issue: severe fps drop on certain maps

https://bugs.winehq.org/show_bug.cgi?id=38166

--- Comment #25 from Kol  ---
I can confirm that the patch from Comment#24 resolves
this bug for Wine-staging 4.12.1. During 30 minutes
of playing sometimes FPS falls to 15 (when many objects
are visible), but never to 1-2. The videocard is GTX660
using Nvidia driver version 375.39. Esync is turned off
because my old system does not support semaphores.
