What's your gpu?
ATi Radeon HD5850 - if you're worried about how hot it runs, it's just because I haven't dusted the heatsink (or anything else in my case) since June and I run my system 24/7. It had a shutoff a couple days ago while playing Blockland, that was the second interruption of uptime since June (the first was the AC breaker tripping from a faulty microwave we replaced in September)
Sky issue: He says in the thread to use v08 shaders, I figured that was since v09 are incompatible with nVIDIA GPUs and I have an ATi one anyway, so I used v09. No sky. Tried v08 versions of Sonic Ether's shaders, works fine.
So hooray for nice looking stuff
