If you’ve ever lost a full kit of loot because your game froze mid-alt-tab while you checked a crafting guide, you’ve probably wondered if there’s a better display option for Rust. A lot of players ask can you play Rust on borderless window to fix exactly this frustration, and the short answer is yes—you just need to know how to set it up correctly, and when it’s the right choice for your playstyle. I’ve tested this mode across three different PCs over the past four years, and it’s my go-to for casual play sessions where I’m also streaming or looking up build guides between raids.
Can You Play Rust on Borderless Window? Official Support & Compatibility
Facepunch Studios, the developer of Rust, has fully supported native borderless window mode for the game since 2018, so you don’t need to mess with mods or third-party tools to use it. It works with all recent game builds, across Windows 10, Windows 11, and even Linux systems running the game via Proton. You don’t need to download any third-party tools or modify game files to enable borderless window in Rust, which means you won’t run the risk of triggering anti-cheat bans for unauthorized modifications.
The only edge cases where you might run into compatibility issues are if you’re running a very old, unsupported version of Windows (pre-Windows 10) or using a custom modded client of Rust that’s not connected to official servers. For 99% of players playing on official or community servers, borderless window mode will work right out of the box with no extra work required.
It’s also worth noting that borderless window works with all standard monitor resolutions, from 1080p 60Hz entry-level screens up to 4K 240Hz high-end gaming displays, so you won’t have to sacrifice your preferred resolution to use the mode.
Step-by-Step Guide to Enable Borderless Window in Rust
Enabling borderless window takes less than a minute for most players, and there are two simple ways to do it depending on whether you can access the in-game settings menu. The first method is through the in-game interface, which is the most reliable option for most setups.
First, launch Rust and wait for the main menu to load. Click the Settings button in the top right corner, then navigate to the Video tab in the settings menu. Look for the Display Mode dropdown menu near the top of the page, select Borderless from the list of options, then click Apply in the bottom right corner to save your changes. The game will flicker for a second or two as it switches modes, and you’ll be good to go. Always restart the game after changing display mode to avoid graphical glitches or input lag, even if it seems to work correctly right away.
If you can’t access the in-game settings because the game crashes on launch in exclusive fullscreen mode, you can enable borderless window through Steam launch options instead. Right click Rust in your Steam library, select Properties, then stay on the General tab. Look for the Launch Options text box near the bottom of the page, type -borderless into the box, then close the properties window and launch the game. It will automatically load in borderless window mode, no extra setup needed.
Pros and Cons of Playing Rust in Borderless Window Mode
Borderless window isn’t the perfect choice for every player, so it’s important to weigh its benefits and downsides before you switch permanently. The biggest advantages are all related to convenience, especially if you use multiple monitors or regularly switch between the game and other apps while playing.
- Instant alt-tabbing to second monitors, browsers, or Discord without the game minimizing or freezing for several seconds, which is a common pain point with exclusive fullscreen mode
- Seamless multi-monitor support if you run stream tools, crafting calculators, or voice chat apps on a second screen while you play
- No resolution reset issues if you crash or close the game unexpectedly, which is common with exclusive fullscreen mode that forces your desktop to change resolution to match the game
That said, there are a few small downsides to consider before you make the switch. The first is slightly higher input lag, usually between 1 and 3 milliseconds, which is almost unnoticeable for casual players but can make a difference for competitive players focused on high-skill PvP. You may also see a 5-10 FPS drop if you’re running the game on a lower-end PC, since Windows has to allocate resources to background apps and your desktop interface alongside the game. For casual players or content creators, the convenience of borderless window far outweighs the minor performance tradeoffs for most use cases.
Another small downside is that you may run into screen tearing if you don’t have VSync enabled, since borderless window uses Windows’ built-in window compositor instead of the game’s direct display output. This is easy to fix, but it’s something to be aware of if you don’t normally use VSync in exclusive fullscreen mode. If you compete in Rust tournaments or focus on high-skill PvP, exclusive fullscreen may still be the better choice for minimal input lag, even with the alt-tab inconveniences.
Fixes for Common Borderless Window Issues in Rust
Most players won’t run into any issues when using borderless window mode, but there are a few common glitches that are easy to fix if you know what to look for. The most common issue is a black screen on launch when you first enable the mode, which is almost always caused by mismatched HDR settings between the game and your Windows system. To fix it, disable HDR in your Windows display settings first, then launch the game and disable HDR in the Rust video settings before re-enabling it on your system if you want to use it.
Another common issue is higher than expected input lag when using borderless window. This is usually caused by Windows Game Mode running unnecessary background processes, or hardware acceleration enabled in apps like Chrome or Discord that are running in the background. Try closing unused background apps first, then disable Game Mode in Windows settings if the lag persists, to cut down on extra processes eating up resources. If you notice screen tearing in borderless mode, enable VSync in both Rust settings and your GPU control panel for smooth gameplay without any stutter.
If you’re running into consistent FPS drops after switching to borderless window, try setting Rust to high priority in your Windows Task Manager. Open Task Manager while the game is running, go to the Details tab, find Rust.exe, right click it, select Set Priority, then choose High. This will tell Windows to allocate more resources to the game over background processes, which can recover most of the FPS difference between borderless window and exclusive fullscreen on lower-end systems.
At the end of the day, the answer to can you play Rust on borderless window is a resounding yes, and it’s one of the best quality of life changes you can make to your gameplay setup if you value convenience over absolute top-tier competitive performance. It takes less than a minute to set up, works with almost all systems, and eliminates the frustrating alt-tab freezes that lead to so many lost raids and loot. Try it for a few play sessions, tweak the settings if you run into minor issues, and you’ll probably never want to go back to exclusive fullscreen unless you’re playing in high-stakes competitive matches.
