Steam has this and the latest tomb raider game for sale (summer sale) for $51. I'm tempted, but I keep hearing performance issues for PC. Has it got better? I know the story is pretty much absent, and that's fine, but how is it now?
To some extent it has been addressed, but definitely not "fixed". I think how much it affects your playing will be dependent on your system and how much you care about a steady framerate.
I just tried again and with about medium settings at 1920x1200 I was getting 45-51 fps most of the time, but there were still random times where it dropped below 30 fps or even into the teens for a couple seconds. Those times usually seem to involve vehicles or something but are totally unpredictable from what I can tell (it's not like it's just explosions, or just vehicles, or whatever).
For reference, my system is getting a little older but was decent: i7-4770K @ 3.5GHz, 8GB RAM, GTX 760 w/ 2GB VRAM and the game installed on my secondary SSD.
Even with the original performance updates a couple months ago I put in over 30 hours into the game, so that didn't prevent me from playing and enjoying the game.
