How is this a valid stack trace with mangled symbol names and file/line information? I've already demangled the name, even though Windows does this for me. The recommended approach to get file/line seems to be to proc "atos" process repeatedly on the symbols to turn them all into file/line. But shouldn't there just be a function call for this, or option to backtrace_symbols() since it's looking up the symbol anyways. I don't get how this external process call would work for iOS, and it seems slow for macOS as well. Compare this with Window CaptureStackBackTrace, and then there is a simple function call via DbgHelp.lib to retrieve the file/line. Am I supposed to somehow use the CoreSymbolicate framework on macOS/iOS?

The macOS screen recording tool doesn't appear to support recording HDR content (f.e. in QuickTime player). This tool can record from the camera using various YCbCr 422 and 420 formats needed for HVEC and ProRes HDR10 recording, but doesn't offer any options for screen recording HDR. So that leaves in-game screen recording with AVFoundation. Without any YCbCr formats exposed in Metal api, how do we use CVPixelBuffer with Metal, and then send these formats off to the video codes directly? Can we send Rec2020 RGB10A2Unorm data directly? I'd like the fewest conversions possible.

Hello everyone! Here with another graphics api question but slightly different. I'm currently looking at 2 SDK's for physics called PhysX and Bullet. The game asphalt 9 uses metal and bullet and I would like to do the same with asphalt 9. With metal 3 out and stable it seems, I would like to use one of these engines for my upcoming metal api rendering engine. Bur there's a catch, I wish to use objective-c or c++ for both the rendering engine and the physics engine as I mentioned above, but not me touching swift(its a good language but i wish to use c++ for game development). What do you guys say about this?

What is the most efficient way to use a MTLTexture (created procedurally at run-time) as a RealityKit TextureResource? I update the MTLTexture per-frame using regular Metal rendering, so it’s not something I can do offline. Is there a way to wrap it without doing a copy? A specific example would be great. Thank you!

I have a Macbook Pro 16 M1Pro 16Gb Ram MacOS 14 Sonoma Beta 4 and GPT 1.0.2 and currently testing Diablo 4 V 1.04 (latest Update on 08.08.2023). The game is awesome and it runs in 2560x1440 in 50-60fps on my 4K-LG Display over HDMI very smoothly, until .... see Problem 1 and Problem 2 Graphics details are in full detail. smooth shadows and even FSR2 works perfectly. Diablo4 needs around 9-11 GB Ram on my system. There are no background activities running! Problem 1: exploring new areas causes Ram Buffer overflow, freezes the screen, and crashes, and a new system reboot is needed. Problem 2: when trying to buy/sell an item, or just the characters menu will be opened, the game freezes. A game reboot is necessary! While running the HUD in games I can see what's going on and could analyze, that while it's the case Problem 1 and Problem 2 happening, The RAM jumps from 9-11 GB to 16-18 GB. This is much more than the System can deliver and cause the screen freezes and crash. Either the whole system reboot or mostly just the game reboot is needed. Would be very nice if Apple could fix/adjusts GPT in the next versions of Diablo 4. Many thanks in advanced

I am facing an issue while playing pubg on 14 pro max with guided access on or while screen recording. Whenever one of these feature is on, there is a lot of fps drops. It doesn't matter if I just started playing or if phone's temprature is high, but there's no 90 fps. With both these features off, I get 90 fps. Can someone help me with this issue?

Hello community this post is for show my complete unsatisfied with Apple specially on developing games for Apples platforms there is lack of support for it for example some new gaming technologies and still that there is no profit or worth from all the work and money invested to develop for it I will close the journey with Apple very unsatisfied I'm going to give opportunities with my business to other platforms that are really worth it and give support to all new technologies in gaming and yes Apple destroyed other gaming makers with their new services like arcade and seems no future for gaming in Apples platforms. Quit goodbye and good luck to everyone.

Hello everyone! After some time to think about I proceed with graphics api, I figured opengl will be my first since I'm completely new to graphics programming. As in my last post you may find, I was speaking on moltenvk and might just use metal instead, along with the demos I found using metal. So for now, and I know this is said MANY TIMES, apple deprecated opengl but wish to use it because I'm new to graphics programming and want to develop an app(a rendering engine really) for the iPhone 14 Pro Max and macOS Ventura 13.2(I think this is the latest). So what do you guys think? Can I still use opengl es on the 14 max, along with opengl 4+ on latest macOS even though is deprecated?
