Zwiftalizer 2.0 Tutorial And In-Depth Analysis Video Hello everyone. Today, I am excited to share with you my brand-new video tutorial and in-depth analysis of Zwiftalizer - the free online tool for reading Zwift game log files. This video has something for everyone, from complete Zwift newcomers to level 60 pros. First, I cover the basics. Then I go over all the metrics in each chart step by step. Also, for the first time ever, I’m showing summary reports that use community data that I’ve been gathering for over two years - over two hundred activities by ten thousand users.
Nvidia dominates the top 10 in the GPU performance charts at 4K Ultra for Zwift. Using the Zwiftalizer data, Jupyer notebook, Pandas and Matplotlib, this post shows how to get the top 10 GPUs from the 4K Ultra category that have a minimum frame rate of 60 FPS, then rank them to get the top performers. Nvidia takes the lead. AMD Vega 64 and RX 580 can do 4K Ultra but did not make the top 10 because they did not meet the high bar of a 60 FPS minimum.
In response to a question about the Zwift graphics engine choices on Reddit, October 30th 2019, game creator John Mayfield had this to say:
Zwift is tailored to lower end hardware, and we’re not shooting for Crysis 3 level graphics because almost none of our users a) care and b) have a machine that can render 100+ riders ontop of a very detailed world.
We optimize for the 90% rather than the 10%.
Zwift runs on a wide range of computer hardware from smart phones to gaming PCs. In 2019, Android support officially launched and tablet graphics now rival mid-range Intel Core i7 laptops. At the high end, ultra 4K is now possible on a budget gaming PC, but would you really want to buy a bulky tower PC in 2020? And do you even need a computer to run Zwift when Android smart phones can Chromecast to a TV?
Update November 2019 None of the config file changes below will increase or decrease the polygon count or detail level in textures. The level of detail is set by the game engine based on your system’s graphics capabilities and can not be overridden.
Watch Ep 47- Zwiftcast Special: How The Alpe du Zwift Was Made on YouTube to learn more about the graphics engine and the adaptive level of detail works.
How well does the Zwift game client run on Amazon’s EC2 cloud computing service? With virtual private networking and the Zwift mobile companion app for pairing sensors, it is theoretically possible to run the game remotely & stream a high quality video rendering of the scene in real-time to a low end computing device or set-top box. I was curious to know how a high end $2,750 NVIDIA T4 GPU, and the new NVIDIA Gaming AMI would perform, so I spun up an instance and ran the client in ‘just watch’ mode for 10 minutes.
Looking to get max ROI on the LHF by COB? I’ve got your 6. GPU - Graphics Processor Unit - the most important resource for real-time 3D rendering. CPU - Central Processor Unit - the second most important resource. Graphics Profile - the level of detail, shadows, and lighting effects in the scene. You can not choose this. Resolution - the size of the picture. Options are Basic (720), High (1080), Ultra (1440), 4K (2610).
In May 2019 I removed the log collection feature on zwiftalizer.com. I removed aging features that would have required a lot of maintenance to bring up to date - namely the benchmarks data collection. The main constraint is my limited free time, not hosting costs (but more on that later). My time is dedicated to my family, then career, then fitness. Hobby projects are frozen. It is unlikely that the benchmarks or the power sources reports will ever come back.
