We've made some rendering optimizations this week, Screen Space Reflections is using indirect dispatches now, the GPU is feeding it's own commands, if you have this component enabled in your scene and just have rough surfaces it should have functionally zero cost now.
In a fully reflected scene you can see good improvements as well, our benchmarks SSR is down about ~0.4ms on average, whereas depth of field is down about ~1ms.We'll keep on iterating on this to get frame time down as much as possible, there's a lot of obvious things to do to make things faster and more GPU driven.
Last week we reported that our crash rates are down. That was fake news, we were tricked by our backend which wasn't recording the stats correctly. Turns out crashes are even slightly up, hovering around 4%, which is obviously too high. We dropped a new batch of crash fixes this week that should bring that number down and will continue looking into it. Stability & Performance remain a primary focus while gearing up for the release.
We've added spawnlists. They're similar to how they were in Garry's Mod. But you're now able to publish them and share them on the workshop. Works with cloud stuff, local stuff, dupes, mounts, anything.
This week, we've added grid snapping to Sandbox. This isn't our end goal. We want to be able to define sockets on models, say a wheel, say a chassis, where you'd be able to weld stuff to those obvious sockets really easily.
Sometimes you may not want the navmesh to generate for your entire scene. Maybe you have a large 3D skybox, or maybe you don't want navmesh on rooftops.
You can now manually specify the bounds within which the navmesh should generate.
Continuing from last week's allocation work, we've kept chipping away at GC pressure. In some places this helped a lot with performance, for example, Cloning Prefabs & GameObjects is now 2 times faster. We've exhausted most of the obvious optimization potential now, but we'll continue addressing any unnecessary allocations we come across going forward.
We also took another pass at native resource leaks, particularly around shutdown. After some previous attempts we were still leaking native resources, and we've fixed a lot of them. Tracking these down also surfaced a handful of general runtime leaks, which we fixed along the way. Hopefully, this will also reduce the large amount shutdown crashes most of us have been experiencing.
We also added a managed leak tracker that reports and force-destroys leaked resources at shutdown, enable resource_leak_tracking for full allocation callstacks and report them to us.

This is a less glamorous blog, but a ton of small fixes and optimizations.. We launched clutter last week, as well as our new menu. Both have been well received, and we're working on improving new features over time.
We've been seeing a steady uplift in players over the last few months, it's been cool to see., considering we're barely marketing the game.We've been giving Sandbox Game more and more love, and as we're gearing up for release, we're treating it as our flagship game. Try it out! Let us know what you'd like to see us add.

Great post. Kudos to the optimization team. Hope the main menu presentation and performance are polished before release. Would be great if loading ran on a separate thread to prevent menu freezes. Also, basic actions like opening the console or pressing the "Cancel" button are still problematic.
