Dear all,
I recently got a new PC (Dell Studio 1749, Intel iCore 3, 2Gb Ram and ATI HD 5650, Win 7 Professional 64bit). I’m trying to run some XNA code I wrote on my previoius PC (an HP with the same OS, 4Gb of Ram, older processor and Nvidia Fx Quadro). Both had installed VS 2008 and XNA 3.1.
The problem I’m having is that simple programs run very very slow (10fps, in some cases even worst), while they were running smoothly on the older PC; I didn’t find an answer looking on the web. Could this be a driver issue? I know the code is not highly optimised, but still it was sound previously.Thanks for any help!

It’s hardly to do with RAM by any chance? You’d 4GB on the old machine and 2GB in your new one.
At the best of times VS can be a bit of a memory hog even if your just editing code and not running / debugging and Win7 requires a fair bit of RAM even just to run IIRC.

2GB RAM is the minimum requirements for Windows 7 (x64), it’s that big a resource hog. So there’s your limit.
You don’t even need a 64bit processor unless you’re using 4GB RAM or more, so get another 2GB in there.

No offense meant, but that is a bit of a stupid statement TBH :roll:.

When compiling, make sure to check the correct configuration is selected.
As you have a multi-core, checkout threading on XNA.
Give processor affinity a try! e.g. for collision loop – if your game needs one.BTW nice machine :wink:
