I'm also running on the newest MacBook Pro, and I noticed that CoH has a lot more issues running in the 32-bit load of the kernel than the 64-bit. I believe the 64-bit kernel has better memory usage processes compared to 32-bit, but don't get me wrong; the game still crashes unexpectedly. Based upon what I'm seeing, on a 2.66 GHz i7 proc with 8GB of RAM, I'm thinking there is a major video memory leak in the Mac version of the game. The only hint of any potential disaster is when the graphics begin to slow down or freeze. And it happens quite suddenly as well.
When i17 came out, and in the 3-4 weeks before it came out, I was using a mac book pro 15" laptop with 2GB ram, 2.4ghz intel core duo, nvidia 8600GT graphics card with 256k memory, and a 250GB hard drive. I was getting a lot more lag and the game started crashing on me a lot. Sometimes I would get a screen freeze and the only thing I could do was either a hard restart or a force quit. Other times the game would just disappear off the screen, without even a message saying the application unexpectedly quit. This was maddening. I updated to the latest version of snow leopard, which only marginally helped.
I decided that if my computer couldn't handle i17, that maybe it was time to replace this 3 year old machine. I plunked down $2600 dollars for the newest mac book pro. This one has 4GB RAM, 2.66ghz intel core i7 processor, nvidia GT330M graphics card with 512k video memory, and a 500GB hard drive.
I have yet to transfer any of my files from my older mac book pro to my new one. I decided to try an experiment instead. The first thing I did after I set up my new machine was download a fresh copy of CoH. I fired it up, thinking new computer, fresh copy of the game, this should solve my problems, right? Well, I am getting less lag that is for sure. But the game is crashing more than ever now, every 20-30 minutes sometimes, and CoH is the only program on the computer! I had ultra mode turned off. Then I tried turning it on - same problem. I dumped the preferences of the game from my user - library - preferences - city of heroes folder, and that didn't work.
My only conclusion is that it's not my computer, it's just the game. The devs must have borked the game for us mac users.
My question, for anyone who is reading this and has a mac, is this: anyone else having this crashing problem? Has anyone figured out a way around it? Any help or suggestions would be greatly appreciated. Thanks for taking the time to read this.
