It seems to get progressively worse with each new version of wine. On 1.6 the effect is immediately noticeable. On 0.9.17, the effect is there though negligible at first. When playing online, other players are quick to point out the "lag." However, the slowed performance in minuscule compared to the most recent versions of wine. 0.9.15 and 0.9.16 may also have this bug, but there wasn't a large enough reduction in game performance when I tried these versions of Wine. It may be the case the reduction in performance in 0.9.14 is so negligible that no one has noticed, not even on older computers like the one I am using. For the record, my hardware stats are a dual core 1.8 ghz processor with 2gb of ddr2 memory, an ATI radeon xpress 1100 graphics card with 256mb of dedicated memory and 256mb of share memory. I am using the open source drivers (as the legacy proprietary drivers are not compatible with any reasonable version of x.org).
Across these different versions of Wine, I'm inclined to believe this is the same bug. The symptoms appear when selecting units and are more severe selecting certain types of units, though the degree of severity varies with whichever version of Wine I use.
