A couple of days ago, someone remarked that the dev texture was looking... jaggedier than usual. They said something about "antialiasing", but it looks more like there's something wrong with the filtering or mipmapping or both. I noticed it too. In the past couple of days I've been experimenting as best I can with settings and trying the game on another computer. Here's what I could discern: Something has definitely changed in the last week or so. Here's one of the official screenshots of MLJ's 72-hour map, and one I took of the same spot for comparison: It's not specific to something on this computer; the other one does it too after the latest game update. The only major similarity is that they both have ATI cards. Neither has had a driver update recently. I have no idea if it was last week's update that caused this or not because, naturally, there's no way to roll anything back. The other computer can't log in to Steam offline, and Linux hasn't been able to launch it at all for months, so I have no way of accessing an outdated copy. I've experimented with changing my filtering settings, antialiasing, texture quality level... nothing seems to do anything. I made a map full of dev textures and loaded it into Half-Life 2 in the hopes that whatever changed didn't affect that engine build. Insanely, it's doing this too now, and I have no way to know how long it's been that way. I'd like to try to get to the bottom of this. If anyone else's dev textures look like this now, please weigh in. Actually, I'd like everybody to check and let me know how it is for you if you can tell, and what kind of video card you have. Mine are a Radeon HD 4850 and... some other ATI card that's newer than that but slightly less powerful. I'll check later.
