Is it a regression?
I am sorry but its a wee bit hard to say tbh, because i recently changed gfx adapter from a GTX970 -> RTX2070, so i upped the quality levels a bit. Setting the same as i used to have ofc yields better performance than i had, so its not really comparable performancewise.
When it comes to water effects i THINK it used to be better quality, but for all i know this could possibly be driver related vs. the new RTX series? (More vulkan extensions and all that).
Right around the time the 8.1.5 patch with the slightly updated graphics engine (d3d11.1 w/multithreading) came, that also broke the d3d12_command_queue_Wait thingy a week later, was around the time things started to be a wee bit slower i think. So between 12-22 march. I swapped gfx adapter around 16 march, so right in the middle of that.
Is it any commits around that date that COULD have done something to some effects like that? If you have a particular commit in mind, i could do a git revert to that and rebuild vkd3d to test perhaps?
