I picked up FTM last night, without applying the patch.. (have to do so about this game). I was looking forward to the apparently better use of cores (explained in one developer article I believe), as I run a quad core 2.3Mhz with a large (but can't remember) amount of RAM, but by 1939 my PC turned into a hairdryer just like SF and before I could save and exit it crashed. Early days yet, but all I can say so far it that you have more thingies on the screen and it feels smooth to traverse the map, but I fear you might be have to endure the usual poor QA these games go through. Early days yet though.
I am confused, why would you not apply the patch? We fixed some crash issues in some of the FTM patches. definitely run 3.05 to get the best experience. Performance is also even better in later patches and there are hundreds of fixes and balance problems sorted after community feedback
