Now here is something that came out of nowhere. Software engineer ‘sultim-t’ has released a Ray Tracing version of the first Serious Sam game, Serious Sam: The First Encounter.
As its description reads:
“Serious Sam TFE: Ray Traced is a port of the classic Serious Sam: The First Encounter (2001), that includes a reworked graphics engine to enable ray tracing support. With the hardware-accelerated ray tracing, it is possible to calculate global illumination, reflections, refractions, soft shadows and other visual effects completely in real-time.”
This unofficial port is available for download right now. And yes, this is a free download, meaning that everyone can download it from here. Now the good news here is that Serious Sam TFE: Ray Traced requires the files from the original game. So even though it’s free, you’ll still have to purchase (and support) the official game.
In order to showcase these new Ray Tracing effects, sultim-t released the following trailer. This trailer shows off most of the game’s Ray Tracing effects. Furthermore, it packs some before/after comparison scenes. It truly looks amazing, so make sure to at least watch it.
Have fun!

Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2.

Huh! Not bad! I like this! Wish it could run on a 1080ti though…
Nice looking bad performance
Hmmmm I have Serious Sam Classics – Revolution (Serious Sam 1 and 2), which is unfortunately incompatible with it…
Also, wouldn’t it make more sense to add ray-tracing to the HD versions first?
It is not possible since the source code to the “revolution” version of Serious Sam isn’t public whereas the source code to the original version of Serious Sam is. If you want a ray-traced version of revolution, the actual developer of the game will have to do it.
Where does this stuff come from?
Where the f*k does this sh*t come from?
I have installed all three versions of this game. Original, RT and HD.
Both original and HD are better. This game NEEDS smoothness to work. The best compromise between eyecandy and smoothness is the HD version, but the original is also better because it supports stuff like EAX, which makes the game sound awesome.
Can’t find ray tracing feature on your GPU. Check if your GPU has it or try to update drivers. What should I do in this situation? I update drivers but keep getting the same message despite taking all the steps
