Performance is quite poor, while the gpu load is very low. The attached screenshot shows that gpu load is proportional to fps, and their pattern is the opposite of the amount of flushes. In typical scenes fps can barely reach 30 while gpu load is around 40% and cpu load is at 60% all the time. I turned off all special effects for this screenshot to show that this only depends on the scene complexity. In fact turning on all the effects don't affect performance much, because the gpu and the cpu are barely loaded.
