Don't let what others are saying change your opinion of the game, you clearly enjoyed it from the look of your post.
You just get to enjoy it even more when you play it through again once it has been patched up.
Yep, I'm enjoying the game a lot. Its uncharted for PC, I've waited so long to get a game like this on the PC. Its such a good game, even the QTE are not bothering me, as uncharted was much of the same, press this to make this happen type of thingy.
But I've fixed the lens flare issue by using window mode, window borderless worked and it did stutter, but using radeon pro and forced triple buffering and v sync fixed it, I've lost a few fps it seems, but now got all the extra eye candy.
As said, Lara can take a heck of a beating, tough lass lol
I'll play through again. Achievements are well hard to get in this game if you don't explore, its a game you can just keep playing...
