I got my hands on Beta 2 today and spent all afternoon playing a 4 player FFA, me against 3 AIs.
I have all of my graphics set to highest running 1360*768 with 4x AA
Specs are
Vista Home Premium 64bit
Intel core 2 duo overclocked at 3.08Ghz
4 GB RAM
Radeon 4870 video card
Asus Xonar D2X sound card
Beta 2 actually has great performance compared to beta 1, no slowdown or stuttering issues anymore in large battles/long games. But after a while of play I got a crash, probably about 30 minutes into the game, I think I was autosave 3 or 4, i don't remember for sure. I relaunched the game and kept going by reloading the last autosave. played some more and it crashed again, repeat, crashed again, repeat. maybe about 5 times so far. This last time, its obviously getting more frequent. I crashed in about 10 minutes or relaunching the game and playing me save file. So the next time, (just before I gave up and came here to report, it had crashed in about 1-2 minutes from reloading the game.
If you want, I can upload the save file and crash dump. but I don't know where the crash dumps are stored. any help?
