You may have noticed Vulkan offers vkMergePipelineCaches. The reason behind this (or at least, one of the reasons) is extreme concurrency (Amdahl’s Law). However, most people create just one VkPipelineCache for the entire app and then forget about. Specially because of how simple it is to setup just one VkPipelineCache […]
Disclaimer: If you work at Samsung Developer Relationships and want to ping me, send me an email to info@yosoygames.com.ar So I bought a new Samsung Galaxy A54 (SM – A546E). On paper it was similar to the one I had (a Xiaomi POCO F2 Pro). I later learnt it’s quite […]
Vulkan isn’t newbie friendly. But something that I get asked a lot are questions that aren’t answered anywhere or is hard to find (i.e. typically in the form of “why are things done this way?”) unless you are familiar with previous APIs (i.e. D3D11 & Metal) and existing HW limitations. […]
Dear ARM, in charge of the Mali GPU: DO NOT REUSE THE SAME DEVICE ID FOR TWO DIFFERENT GPU MODELS.STOP DOING THAT. In case you don’t understand what I’m talking about, here’s an example: in 3DMark for Android Wild Life, the MC4 model has a score 1483, the MP12 model […]
So I’ve been working into integrating Qt Quick (QML) and OgreNext when using the Vulkan RenderSystem for use in Gazebo. Note that I’m talking about Qt Quick. The ‘stable’ Qt Widgets interface (which uses QVulkanWindow) doesn’t have this problem because it’s too simple. There are various ways to perform an […]
By default RenderDoc only downloads resources used by the frame being captured. Resources not used during that frame are not saved. Unless ‘Ref. All Resources’ is enabled, that is. I recently fixed a bug in Ogre where Ref. All Resources would randomly corrupt GPU memory after capture; both in my […]
So I saw these tweets earlier today: Horizon Zero Dawn has been fun.Tells me I have an old driver. Still runs. Takes 30 minutes to compile shaders. I watch the intro cut scene. I think. Better to update the drivers. I quit. Update drivers. Start the game again.And now we’re […]
With new APIs being all the rave (Vulkan, D3D12, Metal), Steam OS pushing for Linux gaming. Even I myself encounter myself doing more and more graphics work in a Linux machine. After quite some time of graphics development on an Ubuntu 14.04 machine it has called to my attention that […]
