Benchmark: Windows 11 vs Lubuntu 26.04 on Llama.cpp (RTX 5080 + i9-14900KF). I didn't expect the gap to be this big.

UPDATE: Vulkan benches arew now included. And yes, I used AI to help me write this post. As a life-long Windows user (don't hate me, I was exposed to it at a young age) I was wondering how much (if any) performance I'm leaving on the table. So I did the sensible thing and run some benchmarks. Setup: OS: Windows 11 25H2 vs Lubuntu 26.04 Engine: Llama.cpp b8929, CUDA 13.1 (downloaded official prebuilt for Windows, compiled myself with CMake on Lubuntu) CPU: Intel Core i9-14900KF RAM: 64GB DDR5 680
