--- Comment #13 from Vincas Miliūnas vincas.miliunas@gmail.com 2011-12-08 18:26:00 CST --- The new patch 0.7.0 has a replay feature, so now it's also possible to reproduce this issue offline.
Currently it's available in the client of the test server, so one needs to install the test patches from here - http://forum.worldoftanks.eu/index.php?/topic/68358-v70-public-test-4/
I'll give a sample of a replay - http://dl.dropbox.com/u/6901628/20111207_2251_ussr-S-51_lakeville.wotreplay
To run it, one needs to pass the reply file location as parameter - WINEPREFIX=.../wot-test .../wine WorldOfTanks.exe .../20111207_2251_ussr-S-51_lakeville.wotreplay
I use this patch to workaround the issue - http://dl.dropbox.com/u/6901628/disable-dynamic-vertex-buffers.patch
Also the "fixme:d3d:wined3d_buffer_preload Too many declaration changes or converting dynamic buffer, stopping converting" message is irrelevant, because in the current configuration it doesn't appear, while the slowdowns are still there.
To reproduce the issue, once the replay is loaded, press left mouse button to enable free look, then turn 20 degrees right from the line where cannon's barrel is pointing at. Having the dynamic vertex buffers disabled (patched) results in smooth 26-30 fps, while having them enabled (no patch) results in 8-10 fps with shuttering.
I use this game configuration (login info was removed) - http://dl.dropbox.com/u/6901628/preferences.xml . It's stored at .../drive_c/users/$USER/Application Data/Wargaming.net/WorldOfTanks
Configuration: AMD Radeon HD 6770, fglrx 11.11 Default WINE registry settings (GLSL enabled), only winetricks corefonts installed.
