You may have more luck by setting VideoMemorySize to a bigger value (see http://wiki.winehq.org/UsefulRegistryKeys). I'm not sure how much video ram is detected by wine, but it looks like it is 128MB (a WINEDEBUG=+d3d log should show it.
Yeah, just bump VideoMemorySize. WoT uses d3d9ex, and I suspect it has "virtualized" video memory like d3d10 and GL, instead of the scheme d3d9 and earlier use where resource allocation just fails once VRAM is full. The way resets work in d3d9ex is a pretty big hint in that direction.
