I’ll add a third game to that list: keeping the other games running well in wine. This game is more challenging than the others, but a lot less fun. Portal is the main problem. It worked perfectly the first time I ran it, and I played through almost to the end. Then it crashed and wouldn’t run again, so I updated wine to the latest. Now it runs, but performance is much worse, and some transparent textures are solid black. A particularly bad effect of this is to turn the whole screen solid black when I get shot, which makes it really hard to react in a way that ends in me surviving.

Luckily (I think) Half Life 2 still works great, so I guess I’ll just have to keep playing that…
