This is a very early stage project to make Rust a first-class language and ecosystem for building GPU code Historically in games GPU programming has been done through writing either HSL, or to a lesser extent GLS.

And while attempts to have been made to create language in this space, none of them have gained any notable traction in the gamete community. Our hope with this project is that we push the industry forward by bringing an existing, low-level, safe, and high performance language to the GPU ; namely Rust.

And with it come some additional benefits that can't be overlooked: a package/module system that's one of the industry's best, built in safety against race-conditions or out of bounds memory access, a wide range of tools and utilities to improve programmer workflows, and many others! We want to streamline our own internal development with a single great language, build an open source graphics ecosystem and community, facilitate code-sharing between GPU and CPU, and most importantly: to enable our (future) users, and fellow developers, to more rapidly build great looking and engaging experiences.

Instead of sharing and copy'n'pasting snippets of TAA code on forum posts, one could simply find and use the right crates from crates.Io. Focus on Vulcan graphics shaders first, then after Vulcan compute shaders Cargo and crates.Io support to develop and publish Spirit crates High-level render graph to take advantage of this, make it easy for users to develop and use rendering effects.

We use this repo as a honored for everything related to the project: crates, tools, shaders, examples, tests, and design documents. We meet weekly over a Discord call to discuss design and triage issues.

Right now because the project is in a very early state of development, we might introduce temporary changes as stop-gap measures, or implement features or APIs that might not work exactly in a way we end up liking. At the moment this means that we make no guarantees about backwards compatibility and have no formal deprecation model in place.

Effectively meaning that currently we only support building from source with the latest main branch in our repository. Our hope with this project is that we push the industry forward by bringing Rust, an existing low-level, safe, and high performance language, to the GPU.

And with it come some additional great benefits: a package/module system that's one of the industry's best, built in safety against race-conditions or out of bounds memory access, a wide range of libraries and tools to improve programmer workflows, and many others! If we do this project right, developers could use open-source crates that provide the graphical effects needed to create beautiful experiences.

Instead of sharing snippets of code on forum posts, they could simply add the right crates. We want to streamline our own internal development with a single great language, build an open source graphics ecosystem and community, facilitate code-sharing between GPU and CPU, and most importantly: to enable our (future) users, and fellow developers, to more rapidly build great looking and engaging experiences.

That's why we've decided to develop this project in the open, alongside the rest of the Rust and graphics programming communities. Focus on Vulcan graphics shaders first, then after Vulcan compute shaders Cargo and crates.Io support to develop and publish Spirit crates High-level render graph to take advantage of this, make it easy for users to develop and use rendering effects.

We'll have weekly meetings on Discord, with open agendas shared in GitHub issues. In this RUST FPS guide, we attempt to demystify the complex world that surrounds system performance, whether you’re a seasoned veteran or a new player.

For gamers, having to deal with slowness, stuttering, and hanging systems at critical moments is the worst. We’ve put together this RUST FPS guide to address this very issue, which is filled with tips, tricks, and a deep dive into all the client settings that can help you improve and maximize your RUST gameplay.

At this level, it’s recommended you turn most features down quite low to maintain a competitive FPS rate. Still, there is undoubtedly going to be some limitations, continue reading to see which ones will have the most significant impact on your system. At this point, you’ll be able to run RUST with most settings around medium to high.

But if you want to maintain a consistent frame rate of at least 60 FPS (or higher depending on your monitor’s refresh rate), you will have to tweak the settings for yourself. Check the Windows start bar and closeout non-essential programs competing with Rust .exe Check the Windows Task Manager and identify any processes utilizing a high percentage of your CPU, Memory, or Network that may be negatively impacting your in-game FPS.

Focus on shutting down programs such as game launchers (Not the one running Rust), internet browsers, etc. Press Windows + R buttons, then type in config and select the “Startup” tab to configure.

These programs can be very dangerous, and manually modifying your game settings will be superior to added additional bloat to your computer. This can take a lot of time, especially if you don’t regularly update your system, but is highly advised.

You might think that setting the system to “High Performance” may make a substantial impact but this often isn’t the case. Setting to “High Performance can cause your system’s CPU to be pegged even during idle time.

Disabling the Windows 10s Gaming Bar, an unnecessary feature that will run in the background by default. This will make sure you’re not bottle necked at a higher and unsupported resolution, causing the GPU to work harder.

It’s also important to understand what hardware bottlenecks exist before you begin down this solution path. If you’re struggling to reach the recommended minimum of 60 FPS, the honest but unrealistic response is to upgrade your hardware.

If upgrading hardware isn’t a viable option, you might consider carefully the servers you wish to play on. Barren servers are a special type of map that culls and simplifies most grass, shrubs, trees, rocks, and other topologies, significantly reducing the stress on a system.

The fewer players and overall entity count can help reduce the stress on your system as well. Many custom maps haven’t been optimized and can have memory leaks that severely tank your system.

Graphics quality, by and large, refers to the various levels of texture and shadow detail in RUST ’s game world. We’ll highlight the big offenders of FPS drops while giving you an idea of what each setting does for you as a player.

To gauge your FPS levels accurately, make sure to include a bit of walking around, particularly near player built structures. If your system meets the developer’s recommended requirements, as our rig did, you are free to choose where you land in the graphics settings.

They are the first settings we recommended reducing if you’re falling substantially short of ideal FPS limits. The settings listed below as Moderate or Low might only contribute to a single FPS gain or drop depending on your system.

If you need to eke out a few more frames to be happy, you can test them yourself to see if they negatively impact your gameplay. Despite its name, this setting refers primarily to the texture quality of objects within the game world.

However, lower-end systems, particularly those low in RAM, benefit significantly from reducing the texture quality. Turning the setting up will blur the edges of shadows, simulating a more realistic lighting effect.

Reduce the number of cascades, and light will shine brighter through trees, and there will be fewer overlapping shadows. This setting at 0 will consider the sun and moon as the only sources of light that can create shadows.

When set to zero, the sea and rivers will lose frothing and foaming textures, instead of dull blue waves. Settings 1 and 2 improve the foaming aspect of rushes and optical surface tension.

While turning the water quality down can improve FPS by a few frames, its impact is primarily determined by how close to the sea you play. Living on the shoreline, you will see a consistent FPS increase at the cost of the wave’s details.

The shader level affects the texture detail of geometry attached to the maps generated mesh. Reducing this setting can have a positive effect on your FPS, at the expense of visually appealing scenery.

If there are any stats worth leaving high, despite FPS drop, the shader level one of them 100 textures are low resolution, to a point where it can negatively affect gameplay (Null Impact) 100 – 200 Textures are more recognizable for what surfaces they represent (Low Impact) 200-300 Improved textures and some light shading (Low Impact) 300-500 Higher detail and visually distinct surfaces (Moderate Impact) 500-600 Even higher resolution with detailed bump maps to give flat geometry the appearance of height and shadow.

Setting the textures to incredibly low will improve game performance for lower-end systems. While this can impact game immersion, the developers have taken measures to assure that it doesn’t affect gameplay.

Much like the draw distance, this setting determines the range at which objects will cast and receive detailed shadows. The close range shadows still render even when set quite low, and thus it has minimum impact on gameplay.

Anisotropic filtering is a setting which bends texture maps at a distance to make them appear more detailed and less blurred or stretched. As a side note, even on high PCs, parallax mapping is sometimes misaligned, leading to an odd graphical effect.

When affected, the player will see a ‘seam’ in the earth textures that appears to follow them around. While this setting has a shallow impact, it has an insubstantial effect on the game graphically, unless you spend a lot of time looking at your feet.

Mesh quality refers to the detail in the 3d models, which make up the Rust world. Reducing any of these settings will scale back the poly-count of surfaces, creating slightly more jagged edges.

This setting affects the detail on particle effects such as smoke, fire, sparks, and electrical discharge. Oil rig, burning helicopters, and during raids are times when particle effects will come into play.

An unfortunate environment that massively affects immersion and gameplay, but has such a significant impact on FPS. It affects the quality of the ground mesh, mostly unnoticeable, but such low impact that it barely makes a difference in where it’s set.

A few of the settings have a substantial impact, and it’s worth going through them to make sure there isn’t one overly affecting your system. Softens the jagged edges of textures and meshes by lightly blurring the separately rendered elements.

Simulates the photographic effect of depth by blurring objects that aren’t in the center focus of the player’s camera. Adds a level of detail which some players may value, but an easy one to turn off and save yourself a few FPS.

Effects might change your system slightly in the few environments that have many embedded light-sources, such as outpost, oil rig, giant excavator. While it can produce an overall pleasant effect, it does require a fair amount of resources for the visual quality of life change, and it's best to turn it off.

This setting adds a bit of cinematic flair by slightly darkening the corners and edges of the screen, entirely up to player preference. If you break a wall or floor with high ribs, they will shatter into many small pieces.

We recommend a substantial reduction depending on your rigs capability so that you don’t lose FPS during raid encounters.
