Heyyo,
Theif 3? really? cause I'm sure with patches I'd run great, it's on the same engine they used for Deus EX Invisible War, and that game ran bad, but once patched I could crank all the settings and I'd rarely have frameloss. Too bad it diddn't have gameplay like the original Deus EX, that game rocked... I wish someone completed the bot for it though, cause there was one in the makings before...
Well, gearbox tried to make this port run better by creating a whole new game engine... but due to deadline constrictions, the optimizations weren't complete... and same goes for the netcode, you get lots of warping, and have to aim ahead of the guy to shoot him down, or behind him if you're inna warthog to compensate for this incomplete netcode... oh well, with good training you can pwn pretty good.
Ok, time to try to stay ontopic here.
I've tried HL2 coop. It's possible, just do what I said in the other thread and then once the main screen's loaded, go in the console and type disconnect, cause the main menu place where it shows a random part of city17 counts as the servers current map, and won't load other maps properly with it still going (yeah, odd how using the map command with already loaded maps doesn't work right with HL2, then again, built in MP was never completed...).
Well, anywho, it worked ok, diddn't lag down my comp too much, but you'll quickly see why MP wasn't complete... like, the model of gordon doesn't even have textures, it's just grey, and very low poly. I'm guessing they did this to lower the intensity that a an extra high poly model with full textures and stuff that you don't even see would lag down the game. So I'm guessing they just made it for hitboxes... anywho, in deathmatch/coop, it comes out cause like, everyone's this model, and all the guns aren't properly positioned to his arm... they're all sticking out from his well, crotch, lmao... I'll have to take a screenie of this next time. Watch the amazing crotch gravity gun lift stuff with ease... oh yeah, pure muscle baby.. LMAO!
I'm gonna replace my gordon model with like, gman, so in MP I'd look cool.
