 ## Optimizations
 
-After profiling I concluded that our project was memory bound and took a lot of time rendering objects that were not visible on screen.

-### Implementation Details
-
-I used ray marching through the froxel grid with the following optimizations:
-
-- **Temporal reprojection**: Reduces noise by blending current and previous frames
-- **Exponential depth distribution**: More detail near camera, better performance overall  
-- **Hardware interpolation**: Leveraging 3D texture sampling for smooth results
-- **Adaptive step size**: Fewer samples in empty space
+After profiling I concluded that our project was memory bound and took a lot of time rendering objects that were not visible on screen. To solve this I added frustum culling which allowed the forward pass to go from 2.30ms to 0.74ms. I also reduced the resolutions used for bloom and fog which led the fog renderpass go from 3.32ms to 0.93ms.
 
-The shader performs 32 ray marching steps per pixel, with temporal accumulation bringing effective sample count much higher.
+I will go more into detail on how I achieved this in my blog. (linked once it's online)
