Wined3d implementation use several critical sections to control aqquire and release resources and enter on critical region. However, SRW api is much more fast than critical section, and it can be reflect on increase of fps.

Does those still apply? Those articles are from 2009 and 2010, wine back then isn't at all comparable to what it is now.

Well, the implementation of critical section and srw is not changed, keep more fast on SRW, because it's use KeyedEvent (implemented on wine)
