Vulkan Hardware Database Quick Filters

 Posted on September 11, 2026  |  Sascha

Rethinking filtering Filtering data is one of the most important parts of any database, and the Vulkan hardware database is no exception. Back in April 2025, I added global filters. These let you enable global pre-filters. While that worked, it was not very intuitive. The settings were somewhat hidden away on a separate page, and once enabled, those pre-filters were implicitly applied to all views that supported filtering. That made it cumbersome, or almost impossible, to adjust filters quickly. [Read More]

Vulkan Hardware Capability Viewer 4.13 with additional feature flags released

 Posted on August 23, 2026  |  Sascha

Better late the never Vulkan launched with a small set of format feature flags for images and buffers. These flags can be used to check if an image or buffer supports a given usage scenario. E.g. sampling from an image or using a buffer as the source for a transfer operation. But as the api surface grew, so did the list of format feature flags, making it necessary to not only use a larger data type for those (64 unsigned bits instead of 32) but to also add a new way of querying those flags.

Improving performance of the Vulkan Hardware Database

 Posted on March 13, 2026  |  Sascha

Tackling performance issues Looking at server statistics, the Vulkan database alone is serving up to 3 million requests per month. A number I would’ve never imagined when I first created this back in 2016. It’s quickly approaching 50k reports and one drawback of such a huge trove of data in combination with that many requests: Performance issues. The database server often can’t handle the traffic and when several people run expensive queries, the database might even run into timeouts. [Read More]

Vulkan Hardware Capability Viewer 4.10 released

 Posted on December 7, 2025  |  Sascha

New client application Version 4.10 of the Vulkan Hardware Capability Viewer is now available for all platforms (Windows, Linux, Android, Mac OSX). Update to Qt6 Just like the OpenCL hardware capability viewer I recently updated, the Vulkan hardware capability viewer also uses the Qt framework for it’s platform-independent user interface. The app has been on Qt5 for quite some time, but for open source users, Qt5 has been EoL since the end of 2023. [Read More]

Vulkan Hardware Database Availability

 Posted on September 13, 2025  |  Sascha

Causes for the limited database availability Some of you might have noticed issues with accessing the Vulkan Hardware Database since end of July. This was caused by a targeted denial-of-service (DoS) attack in combination with ever-increasing rampant AI bot crawling. Note the spike in July That lead my hosting company to take precautionary measures to avoid negative effects to their own services. One such measure was to block access from certain countries, esp.

Improved filtering added to the Vulkan Hardware Database

 Posted on April 5, 2025  |  Sascha

Reworking global filters In the last posting I already hinted at reworking how filtering works for the Vulkan Hardware Database. Almost 40,000 reports across multiple platforms is a lot of data, and being able to properly and easily filter that is crucial for a database. Up until now the only global filter option was the api version, so you could e.g. filter all views in the database to show only data based on devices supporting at least that api version. [Read More]

Cleaning up Vulkan Hardware Database Android reports

 Posted on January 12, 2025  |  Sascha

Vulkan device properties on Android Compared to desktop environments like Windows and Linux, Vulkan on Android is a very different situation. Aside from the obvious hardware specific differences between full desktop GPUs and integrated mobile GPUs there are issues that also complicate data retrieval for my Vulkan Hardware Database. One such issue is device naming and how GPUs and mobile devices corelate. On desktop a given GPU like a RTX 4070 from NVIDIA always reports the same Vulkan properties for a given driver version, no matter who produced that graphics card. [Read More]
