What is the fastest way to get an Inverse Square Root? (Part 2)

Part 1: What is the fastest way to get an Inverse Square Root? Last time I covered what the fastest way was for single precision floating point, but what about double precision floating point numbers? Do they behave the same or will we run into even more issues on older hardware? Since the market starts looking towards 128-bit integers and quad precision floating point numbers, it’s time to also test this one while it’s still ‘fresh’. Read more

What is the fastest way to get an Inverse Square Root?

Everyone who works with a 2D or 3D development studio knows that eventually you will run into hardware that is too slow. Wether that hardware is what you currently have or what your target demographic has doesn‘t matter – you‘ll hit this limit, even if you try not to. That‘s why some clever people came up with different ways to make things faster. Seperating the FPU from the IPU, SSE and AVX and the famous Quake III floating point hack. But which one performs the fastest, and can we make that one even faster? Read more

Full Multi-GPU Support And More! (1.4.2.0 Update for the AMD Encoder Plugin)

Update: Two hotfixes have been released to fix additional issues. The download link has been updated. Today is the day that users with a multi-GPU system can finally use their other GPUs for streaming and recording – and today is also the day that OBS Studio no longer crashes on startup! This update adds full support for multi-GPU systems, fixes the crash on startup bug, fixes Filler Data being stuck on Enabled, makes Delta QP available even when not using Constant QP, fixes some UI things and more. I hope you’ll have as much fun using the plugin as I did creating it! On to the download: Read more

Hotfix 1.4.1.0 is out for the Encoder Plugin!

Turns out that some of the changes in 1.4.0.0 caused exactly what I hoped it wouldn’t cause: crashing on systems with Windows 7 and older. This has now been fixed with the help of Jim (maintainer of OBS Studio). Additionally some crashes have been fixed that were caused by incorrect default parameters which have been changed to the correct value now. Frame Rate & Size should also now be properly applied again. Read more
