Dota 2 OpenGL vs Vulkan FPS – Linux Performance Test

Dota 2 Performance Test – OpenGL vs Vulkan on Ubuntu Linux 18.04 Watch my Video here

Dota 2 is one of the many games officially supported on Linux. But which graphics rendering API offers the best performance? In this side by side comparison I show the FPS (Frames Per Second) difference between OpenGL and Vulkan for Dota 2 on Linux. These tests were run on the same machine using the options toggle to switch between the two API’s. Testing was done at 1080p resolution with the quality slider set to Max.

Hardware

  • RTX 2080 8GB
  • i7 9700K @ 4.6Ghz
  • 16GB DDR4 RAM
  • NVMe SSD

Drivers

  • Ubuntu – 430 nonfree
  • OpenGL 4.6
  • Vulkan 1.1.126

Dota 2

  • Maxed Settings
  • 240 FPS Framerate Limit (Recommend)
  • Patch 7.24

Results

  • OpenGL Average: 114
  • OpenGL 1% Low: 100
  • Vulkan Average: 135
  • Vulkan 1% Low: 101

Recording Settings

Note: The impact of OBS with these settings is as low as ~5FPS. When running the tests I had no additional software running other than OBS and Dota 2. In a real use case even if you don’t record/stream the performance impact should be similar to having Chrome/Firefox open with a YouTube video or Discord ect.

League of Legends Using Wine and Vulkan D9VK Linux Performance vs Windows (Nvidia)

League of Legends Windows 10 vs Ubuntu Linux 18.04 Performance Graph. Watch my video here.

Hey League of Legends players that also happen to be Linux enthusiasts. Today I would like to share a video comparison I’ve created comparing the difference in performance between League of Legends on Windows 10 and League of Legends on Ubuntu 18.04 Linux. This comparison will provides a frame rate (FPS) graph and and a side by side comparison of performance between the two systems handling the same replay from League of Legends patch 9.24 from Late December 2019.

Hardware

  • RTX 2080 8GB
  • i7 9700K @ 4.6Ghz
  • 16GB DDR4 RAM
  • NVMe SSD

Drivers

  • Win10 – 441.08 WHQL
  • Ubuntu – 430 nonfree
  • Wine: lutris-lol-4.20-x86_64 D9VK/Vulkan Enabled

League of Legends

  • Medium Settings & Shadows
  • 240 FPS Framerate Limit (Recommend)
  • AA Enabled Patch 9.24B (Late Dec 2019)

Results

  • Windows Average: 154
  • Windows One Percent Low: 120
  • Ubuntu Average: 140
  • Ubuntu One Percent Low: 106

Recording Settings

Note: The impact of OBS with these settings is as low as ~5FPS. When running the tests I had no additional software running other than OBS and League. In a real use case even if you don’t record/stream the performance impact should be similar to having Chrome/Firefox open with a YouTube video or Discord ect.
