A very curious ArsTechnica member (Nivenhbro/jjwalker), as far as I can tell, got very bored one day and decided to start project Float32. The end result of all this concentrated boredom and effort is an extremely well done S.T.A.L.K.E.R. mod. Of course, as we all know, third party add-ons may easily be broken by the makers of S.T.A.L.K.E.R. with patches.
The modification boasts better bump mapping, adds real time calculated specular effects, improves full reflection vector calculations, and boosts soft shadow quality. At the same time of offering all these improvements and more, the mod improves efficiency of the game, increasing frame-rate by no less than 20%, which is no small feat. Using next generation (and NDA) hardware, The Inquirer claims that they see a 20-25% improvement in frame-rate.
If you want to try this modification for yourself, save a copy of your original S.T.A.L.K.E.R. files, and head over to
