Sobre el proximo Parche: 5.19.11 - Patch Next Week:
Update: the team notes the patch actually will address performance, for both memory leaks which degrade performance over time, and slow performance while indoors. Overall and especially outdoor performance seems to be the issue for most people, however -- it's not yet known if this will be addressed quite yet.
As noted yesterday, a patch for The Witcher 2 is in the works, though will be taking a little longer than expected, arriving sometime next week.
Besides the mouse inversion fix, keyboard rebinding will be improved and "assorted other fixes" will be included; 16:10 support is expected to arrive at a later date. Unfortunately there's no mention of performance optimizations, but remember NVIDIA users should be able to do alright with the latest beta drivers, while AMD users can expect a hotfix driver sooner than later; Crossfire users can expect an application profile soon, too.
