Hello, I would like to hear about your experiences of running XSI in mixed 64 and 32bit enviroment. We are considering purchase of some new rendering machines and we are currently looking for Dual Quads HP machines. But fear is, that in under 32bit XP we would run into problems with memory limitations of 32bit executables and we will not able to utilize their power effectively. So we are considering to run 64 bit XSI on 64 bit XP. On other hand we are not ready to do full studio switch to 64bit. Its big problem to run both versions of XSI together rendering one job? I suppose that we will have to keep Workgroups for both platforms separate? I would really like to hear some comments.
