First of all I want to say that there is no way I will go with DGDK when the .Net version will come out soon. C# is so much more fun to code then C++, I never want to go back!

Here's my question: From the DGDK website I can see that the DGDK is 0.5% - 107% faster then DBP (with an average of 31%). Where will the DGDK.Net be speedwise?

my guess would be somewhere between dgdk and dbp but probably right around the same as dgdk. i'm not sure apex has done comparisons yet.

Its 9/11 - but its FAKE 9/11 Ts=SQRT(Df/16)

I just read all 8 sites from the pinned thread and that DGDK.net is a .Net wrapper for DGDK. The overhead shouldn't be too much, I guess it will be the same speed or even a bit faster because of the JIT.

Not sure this assertion makes any sense...

I have vague plans for World Domination

I have found that the general performance of the DGDK.NET toolkit, is fast, but it also boils down to efficient use of the .NET framework itself. For example, using Generics for managed lists and such, are much more faster and efficient than using Collections. Therefore, good programming and code efficiency can make a big difference to application performance when used alongside the DGDK.NET toolkit.

I found that my Asteroids example (not available yet due to beta testing restrictions) will run much better if I convert the CAssets class to use Generics instead of the current collection functionality. CattleRustler will agree highly on this as well.

I will appologise at this point for delays, but beta testing has gone very well so far, I am just tied down with the documentation, although this is now nearly complete.

Paul.

@Miguel Melo: It makes sense. The JIT does optimize when it translates the IL-code to machine code. Therefore an game might run faster on some machines, because the JIT takes care of optimizations.

I would expect to see it being slightly slower than the assembly generated by C - however, it shouldn't be that much - .Net is supposed to be pretty fast nowadays.

That would make sense since it was I who turned you onto Generics

I still haven't cured the common cold ye... oh wait... Generics, thought you meant Genetics.
