I apologize for the click-bait title. But I have your attention now. I was surprised I could barely find information about this online; so I figured I’d have to step forward. If you google about percentile calculation, e.g. 95% percentile, they will tell you to do this: That is, sort […]
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 […]
Ok that was a flashy clickbait-y title! What? You didn’t like it? I’m proud of that one! So I recently tried to implement 16-bit floats into our shaders. I knew it was untested. What I was not prepared is… how untested everything is! We use macros like #define midf min16float. […]
If you browse the capabilities of the GeForce 1080, you’ll notice it exposes 8 memory types on heap 1 If you browse an even older GeForce GTX 680, you’ll notice it exposes 2 memory types on heap 0 and 8 memory types on heap 1, often with propertyFlags = 0 […]
So I got a question from a fellow graphics dev, where he was waiting to get his hands on an M1 Max to see how much he can push on it, and his main question was: Should I treat it like a mobile GPU or Desktop GPU? So what does […]
So I got Radeon 6800 XT working on Ubuntu 18.04.5 LTS but it wasn’t hassle free, given the card is too new To get it working, you’ll need the following: Mainline kernel 5.11+ or newer (5.13+ recommended) Newer firmware Kisak PPA Optionally 5.13 patch for Full RGB option (discussion) Update: […]
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 […]
