> ABOUT_

Started with arcade machines.
Never stopped taking things apart.

Rudji Games is a small, senior studio from Belgrade. 27+ years of engines, graphics and systems code — now shipping games and helping teams around the world make theirs faster.

The Company

Founded in 2023, Rudji Games creates games and provides game development tools and services. The company takes its name from the founder's son, Rudji, who shares an enthusiasm for gaming and puzzle-solving.

Based in Belgrade, Serbia, Rudji Games works with teams all over the world, bringing decades of experience in low-level graphics and systems programming to every project. Since launch we've contributed to titles like Mortal Kombat 1, WWE 2K25, Splitgate 2 and BeamNG.

The Founder

Milos Tosic has 27+ years of professional experience in engine, rendering and systems programming, with roots in the 1990s demo scene. He co-authored the world's first GPU-driven rendering engine, presented at SIGGRAPH 2015, and has recently worked as an embedded principal and graphics engineer on UE5 titles including Splitgate 2 and MindsEye.

His childhood curiosity about how arcade machines operated drove his career toward game development — a path that has led to work on major titles across consoles, mobile, and PC, and to MTuner, a memory profiler with 2,700+ GitHub stars, used by developers worldwide.

Technology

Rudji Games develops with its proprietary iMagus™ engine, built for modern game development with a focus on performance and flexibility.

> HOW WE THINK_

What we believe

Measure, don't guess

Intuition finds suspects. Profilers find culprits. Every change we make comes with a number.

Know the whole stack

From shader to allocator to the OS scheduler. Performance problems rarely respect module boundaries.

Senior by default

Small on purpose. You talk to the engineer doing the work — no account managers, no hand-offs.

Leave teams stronger

Tools, docs and knowledge stay behind when we leave. The goal is that you don't need us for the same problem twice.

> PLAYER 2?_

Let's build something fast together.

Whether it's a performance problem, a port or a new game — we'd like to hear about it.
