We've also played a lot of Quake4, including a little bit of clan arena on Paul's server (which no-one else but me, J and Paul managed to make it for). I miss q4max when I'm playing on the patched servers - I get ~20fps boost from the vertex lighting mode, which means I'm capped most of the time, and it does make playing quite a lot easier. But I've found some tweaks to get things faster - no weapon showing on the UI, no muzzle flash, no projectile lights, simple items. And I'm gradually getting used to telling the difference between weapons & ammo packs with the simple items, and working out what weapon I have from the crosshair (otherwise I tend to get surprised when I blow myself up with the rocket I didn't realise I was firing ;) ). We're likely to pick up stereo headsets sometime soon, too - the public server we play on most has quite a few people who talk. (Though we have to be in windows to hear it, which is annoying - they've not put voice support into the linux client).
I only left the house briefly yesterday, mostly to help J take some of the stuff we'd cleared out of the box-room to the tip (like the printer that died sometime ago and we'd never bothered to dispose of). And also to go to the co-op & get some beer to have with dinner :)
And once again we stayed up rather too late playing games, so I'm rather tired now.
