A hotfix has been pushed live to adjust the displayed download size.
Changes:

• Fixed an issue that was causing the download size of Half-Life 2 RTX to appear larger than it actually was. The correct download size of 44.1GB is now displayed during installation.

Investigating Reported Issues:

• We are investigating an issue where some game overlays can cause crashes when used with the Half-Life 2 RTX Demo. We recommend disabling overlays before starting the demo, but can confirm players looking to measure performance can use FrameView [www.nvidia.com]without risking a crash.
  
• Some players are reporting a crash during the first-time they start the game, due to issues with shader compilation. If you experience this, please start the game again.

We are also reading your feedback, and will apply patches for reported bugs in the future. Here are a list of known issues we are currently tracking:

• Steam Hotkey for Screenshots (F12) will crash Half-Life 2 RTX. We recommend using NVIDIA app’s Alt+F1 screenshot feature, NVIDIA app’s Alt+F9 video recording feature, or OBS “Display Capture” to take screenshots and video.
  
• When Desktop Capture is active in NVIDIA app’s settings (Alt+Z --> settings cog --> Video capture) video recording can at times cease working in the Half-Life 2 RTX demo, requiring users to restart the demo. To prevent this, please disable Desktop Capture in NVIDIA app’s settings.
  
• Father Grigori occasionally will not throw the player the shotgun in d1_town_02. If this occurs, please reload a save from before exiting to the rooftop.
