Fixes and Enhancements
Remote Access Server Server (RASS) Fix
We squashed a pesky bug that caused a missing library message in the Remote Access Server (RASS). Now, your remote access adventures can be smooth sailing!
Faster, More Reliable Camera Canvas
Introducing the new and improved camera canvas! It’s faster and more reliable, thanks to a revamped backend object. This upgrade ensures seamless image display across robot skills while boosting performance and cross-thread reliability. Your robot’s vision just got a serious upgrade.
GPU-Powered Screen Capture for RASS
We’ve turbocharged the Remote Access Service (RASS) by leveraging GPU DirectX for screen capture. Say goodbye to excessive CPU usage! With this change, CPU load during RASS is reduced by a whopping 5-10x, letting the GPU handle the heavy lifting. Efficiency never looked this good.
