It’s been an entire year since Portal: Revolution’s release, can you imagine?
Developer commentary
Added full developer commentary from most members of the team, featuring over 200 nodes.
Engine
Volumetric lighting
Updated volumetric lighting effects to require less samples, which improves performance while also looking better. We could measure speedup of up to ~46%. The new implementation also allows you to select different quality options and their look has been improved to work from more view angles
Other
- sv_max_allowed_developer is now set to 2 by default so developer cvar can now be changed during gameplay
- Fixed mat_fullbright now properly working with static props and overlays
- Various crash fixes (Thanks Strata!)
Map changes
We updated a lot of maps. Besides the usual bug fixes detailed below, here are some of the highlights
This corner of sp_a3_vactube_flings has been opened up. Players would often not find the cube dropper since it was hidden away, so we hope this change fixes that.
We extended the puzzle in sp_a3_vactube_cuberemove a bit
The button platform in control room 3 has been extended
More lights were added to this puzzle to improve visibility
A cable was added here to visually connect the door to the disk reader
This cut sign has finally added
Low quality graphics settings
We improved support for low graphics settings. Some materials, like water, appeared broken which are now fixed. Some materials would also fail to respect lower graphics settings and render at full quality. Some commonly used models will now render at lower fidelity when low graphics settings are enabled.
