I’ve been having a problem with Visual Studio creating lag whilst debugging. The problem occurs during a game I’ve written where, when you shoot it creates about a second of lag. Weirder still, I wrote this same program before and the lag didn’t exist, very few things have changed in my new program.
The ultimate weirdness is that when I do a performance profile, it suddenly works awesome. Ditto if you go into the solution directory and launch either the debug or release version directly. Anyone know why this is happening? I can’t work on my game until it’s resolved. 🙁

EDIT:
The issue was occuring around a bit of code I use to parse XML files. The issue was that I overused try-catch and it caused considerable lag.
If your code throws many exceptions which are caught, VS2010+ (.NET 4) will be very slow with debugging compared to VS2008 (.NET 3.5). This is known issue.
This is more likely to happen when debugging unit tests that are heavy on exception testing.
