RE: C# scripting

The current CLR doesn't appear to optimize floating-point math much
at all, so no matter what the languate, it's unlikely to be well suitable
for most 3D gaming applications.

Subject: Re: [GD-Windows] C# scripting


I should clarify my question as I don't think I was clear.

It seems that JScript combined with JIT is an efficient solution.  A fast
scripting language like Lua outperforms a traditional Javascript
implementation enough that it is worthwhile to use Lua for our intended use
in a realtime game.  So I'm wondering if anybody could comment how C# using
JScript might stack up against a C++ app with embedded Lua in terms of raw
performance (Or any other language/script combo, my point being to benchmark
between native code and "managed" code).

Hmm... maybe I made it even more unclear? :-)

our current PlayStation2 engine that uses Lua, it must be a magnitude slower
to use JScript inside a JIT environment isn't it?  Would you recommend
developers to implement their own scripting solutions?
