Leadwerks faster in BlitzMax than C++

[Cole Chapman]

Very attention grabbing title. This is either a confirmation that the code is not accurate or its a confirmation that the title is correct (though that goes against what I know). Code is below. If anyone needs, I can upload both that includes the exes.

Some flaw in the code maybe?

You'll have to understand, that the first argument will be that it's because BMax made the DLL, or that the engine is made with BMax. This topic WILL lead to a dead end.

In the BMX code you are just rendering to a simple gbuffer. The C++ code is using the Framework object, which has a lot more effects and uses HDR by default.
