First of all I would like to think Studio 397 for all the hard work they're doing on rfactor 2. Since the DirectX 11 update has come out I have seen my frames drop from 100 + into the mid twenties. However in four days, three really, they have been able to make adjustments and post hot fixes that have brought me back up into the mid-to-upper 50s and even 60s. Well not every piece of eye candy is on it does look fantastic, and it runs a lot smoother then the dx9 version did. Under the X9 I had stuttering occasionally that was enough to cause concern. Under DX11 it has been buttery smooth with only the very very occasional hiccup. They have clearly been paid attention to what the posters in the forums have been saying. And the people free with the forms have also been very attentive to upload logs and other things that the developers have requested them. I think the community deserve some credit here as well as they have been pretty communicative wood Studio 397 in expressing the problems that they were having and then doing a studio 397 has asked to try to help squash the bugs. Again, I would like to think Studio 397 for all the work that they're doing and wholeheartedly support work that they're doing to make this great Sim even better.
