Well i also dove into TR this Sunday (finally) and so far loving the gameplay
Though the QTE's tend to be a pain in the ass...
I've run into a few technical issues as well though, to keep things playable i had to drag texture filtering to ani x1 and turn off SSAO (thankfully only minor things since i hardly notice the difference). With vsync off and AA off i'm running the game on 25-45 fps (most of the time it stays between 30 and 38) which is fluent enough for me
I did notice some weird glitches with textures and lightning where things sort of shift right a bit and then snap back to how they are supposed to be (kind of hard to explain), but that seemed fixed when i upped AA to FXAA, which didnt really seem to put a dent in my FPS.
I also have the black screen freeze though, but so far it only happened twice. The game just freezes entirely and the screens turn black (second time the image recovered on only the right screen), core speeds of both videocards dropped back to 500 MHz and it dumped the memory (went from ~2000 MB down to like 100 MB). I could still CTRL+ALT+DEL but after clicking anything there everything just froze, which left me turning it off and on again as the only option.
Thankfully that only seems to happen after about 3 hours of play, i've not noticed any progress loss either.
