Core 2 Duo processors and Mastercam

[Jeremy Haage from MCAM NorthWest]

Is anyone out there running a Core 2 Duo processor with Mastercam X2? I'm trying to troubleshoot a problem with slowdowns on a system using an E6400 processor & ATI FireGL v7200 video card when running multiple sessions of MCX. I expect the usual graphical anomalies associated with the ATI video cards but am not sure it would contribute to this slowdown in multiple sessions. Comparison is being done between this computer and a Pentium D with an Nvidia card. The Pentium D + Nvidia card does not experience the slowdowns when running multiple sessions.

 

If anyone has any insight into this I would appreciate any feedback. If you're running a Core 2 Duo processor and multiple sessions work fine please let me know.

Jeremy,

Have you already set "affinity" for the multiple sessions? If I recall correctly, you need to split the sessions between processors. This has been an issue many times, try a search for more info.

I had the customer try setting processor affinity with no improvement in the slowdowns. The RAM on each machine is 2GB. Using standard 50% toolpath buffering in X2. Tried disabling hardware acceleration, etc.

MC has always liked Nvidia cards better. I had to get rid of a Fire GL card for a (lesser) Nvidia card when I got dual LCDs to make MC run right.

Fire GL is probably the issue. Do a search on them, I know I've seen previous posts on them specifically
