Does dmd omit framepointers in release buidls? (on windows)
If yes is there a way to turn it off?

Yes.

I think the only option is not to use -release.

(For the record, I also don't think that putting stack frame generation  
and disabling of asserts/etc. behind one option was a good idea.)

obviously in release build. Because of the omitted framepointer the 
profiler can often not walk the callstack correctly and this results in 
wrong profiling output. Not building with -release would not really 
result in representable results when profiling.

 You should try the good built-in profiler.
 It's an instrumenting one and besides a severe slowdown in certain

 profiler.

As I want to profile a realtime 3d game the builtin profiler is not 
usable for me, as it slows my game down to unplayable framerates. Using 
a sampling profiler however is possible without a gamebreaking 
performance impact.
