nothing should stop you from writing video games in Haskell since the
control logic of many video games is written in e.g. a scripting language
like LUA :-)
sure if you want to write a physics engine in Haskell, that's something
else.
but I've worked with people that wrote physics engines in C/C++, and they
also had to hand optimize specifically for a certain compiler to get things
fast.
so some manual tweaking to Haskell could be acceptable if you want to get
high performance. and I hope that in the future the Haskell compilers will
optimize more and more and more...

Hello Thomas,

I'm not sure what you're getting at Bulat √ it's been demonstrated that ghc is slower than gcc for most cases at the moment (many benchmarks will back this up), *however*, it's also easily verified that ghc has had significantly less effort directed at it than gcc and other imperative compilers, thus, there are many places it can improve greatly.
of course. what fool will say that ghc cannot be optimized the same way as gcc? if we spent the same amount of time for improving ghc back-end as was spent for gcc (tens or hundreds man-years?), then *low-level* Haskell code will become as fast as C one, while remaining several times slower to write
In this case, you've pointed out a really great source of heavy optimisation. Thanks a lot :) Now perhaps it might be an idea to be constructive, rather than trying to stand like nelson going "HA HA" at the people with the inferior compiler.
ghc is superior compiler and it's my main instrument. but it can't make coffee and doesn't contain sophisticated code generator. it's why i dissuade from writing video codes in haskell and i don't like situation when someone too lazy to test speed yourself tell us tales and attack me when i say about real situation
