--- Comment #30 from Vincas Miliūnas <vincas.miliunas at gmail.com> ---
I've been out of the loop with things related to World of Tanks or WINE for
almost two years. But I did a test to check if the issue is still present.

Radeon driver on the 3.17.4-200.fc20.x86_64 kernel only rendered WoT as a
collage of random graphics memory with music playing in the background.

I ran the newest WINE git wine-1.7.33 as well as the previously affected
1835e2f5baa376eab95c760951fcc6a3612aa6cd and older commits. With and without
using the workaround -

My old post says WoT 0.7.0 needed only winetricks corefonts, however the
current WoT 0.9.4 requires winetricks d3dx9 (looks like it no longer bundles
the dx dll). Testing was done with a clean WINEPREFIX otherwise.

With the same AMD Radeon HD 6770 and the newest 14.12 fglrx driver I cannot
reproduce the performance degradation issue (in fact the workaround reduces
performance). In every setup I get ~20+ FPS looking at a geometry-rich scene in
two replays tested, which is the same or slightly better compared to what I as
getting two years ago with the workaround. Could be a change in newer WoT
versions, or a fixed bug in fglrx, or maybe the influence of winetricks d3dx9.

Well, as for a performance level, I would say that the two year old commits
around the time of 1835e2f5baa376eab95c760951fcc6a3612aa6cd give ~1-2 FPS more
than wine-1.7.33.

Anyways, it doesn't look like a WINE bug, I would say RESOLVED/UPSTREAM is
fitting here.
