Another: "Using Halo imagery in a call to ‘destroy’ people because of their immigration status goes way too far, and ought to offend every Halo fan, regardless of political orientation”

When I started work on my @vulkan.org #Vulkan C++ samples almost 10 years ago I made some non-optimal decisions esp. around sync and command buffer recording. Finally fixed those and did a write-up with a small retrospective at www.saschawillems.de/blog/2025/08...

Reminder to use gamma correction in your Gaussian blurs for that rich bokeh effect.
Inside the blur loop:
blur_sum += pow(tex_rgb, GAMMA);
And encode for the final color:
gl_FragColor.rgb = pow(blur_sum / blur_num, 1.0/GAMMA);

The tech and graphical advancements in Assassin's Creed Shadows are mighty impressive: Micropolygon geometry, fluid wind simulations, ray traced global illumination and so much more. How do they all work and compare to AC games of the past? Find out in my video below!
