--- Comment #3 from Matteo Bruni matteo.mystral@gmail.com --- Actually you should run Wine with WINEDEBUG=-all when you're not debugging some Wine issue. That doesn't simply silence traces, it also e.g. disables many error checks in wined3d. That's going to be even more significant as further performance improvements will be introduced in the future.
