MSI Kombustor Download
Download MSI Kombustor for Windows and put your graphics card through demanding stress tests. Check GPU stability, monitor performance, and test your system under load.
What is MSI Kombustor?
MSI Kombustor is MSI’s burn-in benchmarking tool that’s designed to push your graphics card to its limits so you can identify overheating, crashes, or instability issues. Built on the FurMark engine, it supports OpenGL and Vulkan to run heavy, continuous workloads that push the GPU to maximum heat for accurate stress testing and stability checks.
The Kombustor MSI includes multiple test scenarios (over 15) that target different parts of your GPU hardware. They’re available in two modes: demo/stress test mode (runs until the user stops it) and benchmark mode (runs for 60 seconds and displays an MSI Kombustor score). The tool also includes artifact scanning to detect visual glitches. Alongside GPU testing, it includes a CPU burner that loads CPU threads to simulate full system load, mainly for combined stress testing and checking power and cooling balance (not for CPU stress testing). Real-time monitoring shows temperature, clock speeds, and usage.
It is widely used with MSI Afterburner for GPU stability tests. The latest MSI Kombustor v4.1.36 supports NVIDIA GeForce, AMD Radeon, and Intel Arc GPUs. Want to see if your PC’s cooling can survive hours of maximum stress? Use Kombustor to test your GPU stability and check for crashes before you start gaming or rendering.

How does MSI Kombustor work?
MSI Kombustor is a GPU burn-in and benchmarking tool built on the FurMark engine. It renders continuous heavy 3D scenes to push your graphics card to maximum load while tracking temperature, stability, and performance in real time.
The Main Interface
Opening Kombustor gives you a clean window. Select a stress test, pick a resolution, choose OpenGL or Vulkan, and enable fullscreen or windowed mode. Once started, the screen switches to a 3D scene, a spinning donut, MSI logo, or geometric sphere, while live GPU stats display at the bottom. GPU usage will immediately climb to 99–100%.
Graphics Tests
The stress test dropdown gives you over 15 options. Every test name starts with (GL) for OpenGL or (VK) for Vulkan. That prefix tells you which API the test uses before you even run it. Tests fall into three types:
GPU Burner Tests
Tests such as FurMark-Donut and MSI-01 create a heavy GPU workload and generate maximum heat.
VRAM Tests
These tests fill graphics memory to a fixed amount, from 1700MB up to 6500MB, helping expose VRAM instability.
Tessellation & Physics
TessMark and MSI-02 target specific GPU subsystems, including tessellation and physics processing.
For a full breakdown of every test, see our complete MSI Kombustor test types guide.
Modes of Operation
Every test runs in one of two modes.
Stress Test/Demo Mode
This mode runs indefinitely until you press ESC and has no score. Overclockers use it to validate stability after adjusting clock speeds.
Let it run for 15–30 minutes. If nothing crashes, artifacts, or throttles, the GPU is stable under that workload.
Benchmark Mode
Benchmark mode runs for exactly 60 seconds and produces a score based on average FPS across three resolution presets: 1080p, 1440p, and 4K.
A higher score means better performance. However, there is no universal “good” score. Compare results using the same GPU, resolution, and test.
See our benchmark scores guide for a full comparison.
Artifact Scanner
The Artifact Scanner checks every rendered frame for visual errors like flickering, dots, or distortion. The on-screen counter shows current artifacts found and total artifacts for the session.
Any value above 0 means instability, usually caused by high clocks or poor cooling.
Real-Time Monitoring
Kombustor shows live GPU stats during tests, including core temperature, VRAM temperature (NVIDIA), load percentage, fan speed, and power draw.
The GPU monitor graph helps track heat changes and quickly spot thermal throttling under sustained load.
CPU Burner
Many users wonder, “What is MSI Kombustor CPU Burner?” It is a basic CPU stress tool that loads selected threads.
Most users skip it for dedicated CPU tools like Prime95 or OCCT. Its most practical use is running it alongside a GPU stress test to check whether your power supply can handle both components pulling maximum load at the same time.
MSI Kombustor Features
MSI Kombustor includes focused features for GPU stress testing, thermal analysis, and overclock validation. Here’s why it remains useful in 2026:

Benchmark mode runs for exactly 60 seconds and displays a score automatically. Stress test mode runs indefinitely until you press ESC manually.
For quick overclock checks, 15 minutes is sufficient. For new builds or full stability validation, run it for 30 minutes. Never exceed 30 minutes unnecessarily.
Kombustor is actively maintained and available via Geeks3D. It remains a widely used GPU stress testing tool, commonly bundled with or launched directly through MSI Afterburner.
Start with (GL) MSI-01 Burn-in Mode or FurMark-Donut at your monitor’s native resolution. Run for 15-30 minutes and watch for artifacts or crashes to confirm GPU stability.
Benchmark mode runs for 60 seconds and produces a score. Stress test mode runs indefinitely with no score and is purely for monitoring crashes, artifacts, and temperature stability over time.
Use your score as a baseline, then compare it against other users running the same GPU. A significantly lower score points to thermal throttling, outdated drivers, or an unstable overclock.
Yes, via the built-in CPU Burner button. It stresses selected processor threads but does not use AVX instructions. For serious CPU stress testing, pair it with Prime95.
Kombustor is safe on any GPU with adequate cooling. If there’s no cooling, it can cause irreversible damage. Monitor temperatures throughout; stop immediately if GPU temps exceed 90°C.
Both share the same FurMark engine. Kombustor adds Afterburner integration, an artifact scanner, VRAM temperature monitoring, and multiple API options, making it the more complete package for overclockers.
