   Any tools for debugging performance? (C++)
  I'm getting some lag in my game I made in OpenGL, VS2008 C++, but I can't really point out what function or for loop is slowing down my game that's taking a bit to calculate.What are some C++ tips or tools I can use on VS2008 or 3rd Party application to tell me performance on a function, to assist me on finding what's taking time to calculate?I even I'm using multithreading for a function to help performance, but it's not doing much to performance witch this for loop would only go 256 times just for a if statement that determines when to assign or update variables.Thank you, I hope your recommendations work!-Ajm   
  For profiling, you might take a look at AMD CodeAnalyst. It's free, and although some features will only work on machines with AMD processors, the time-based profiling feature should work with any processor (AFAIK, at least).   ;  gprof   ;  What you call "debugging performance" is usually referred to as "profiling". That might help your Googling. :)   ;  I can't figure out how to use Code Analyst with VS2008. It doesn't show stats of the source code's hot spots anywhere.Even trying VS2008 Analyze menu doesn't seem to show where I can use it's profiler.   ;Quote:Original post by ajm113I can't figure out how to use Code Analyst with VS2008.

I downloaded the 30 day evaluation last week and it's very interesting to see the results! I won't be optimising without it again :-)
