Rainbow Six Siege X is a competitive shooter where milliseconds win matches; so graphics settings stop being an aesthetic preference and directly affect play quality. High frame rate influences everything from aim responsiveness to motion readability. But when it comes to Siege X, the first question isn't the settings menu—it's the platform: which device can you actually run the game on? For Steam Deck owners in particular, the answer isn't encouraging, because the anti-cheat solution the game uses isn't compatible with Linux. In this guide, we cover both how to achieve high frame rates on desktop PCs and how to work around handheld limitations.
Which Devices Can Run Siege X, and Which Can't?
The biggest platform surprise for Rainbow Six Siege X was Valve's handheld. Because the game's anti-cheat system isn't compatible with Linux-based operating systems, Siege X currently can't be played on SteamOS. So if you're determined to play on Steam Deck, you'll need to install Windows on the device; there doesn't appear to be another way around it. The same restriction doesn't apply to other Windows-based handhelds: ROG Ally X, MSI Claw, and Lenovo Legion Go aren't affected by this issue and can run Siege X directly. And since the game has built-in controller support, you can comfortably play these devices in handheld mode.
If you choose to install Windows on the Steam Deck, you'll need to be more conservative with settings. The recommended approach in this scenario is to stay at the “Low” graphics preset and disable AMD FSR. The reason is simple: aggressive upscaling blurs the image and makes target acquisition harder; while already struggling with frame rate on the handheld's limited power, you don't want to lose image clarity too. In short, playing Siege X on Steam Deck is possible, but not out of the box and requires extra effort. Windows-based handhelds, meanwhile, offer a much smoother experience in this regard.
The Logic of Settings: Why a High Average Isn't Enough
When tuning competitive shooters, most players look only at average FPS; yet the real deciding factor is the 1% low. This value shows the frame rate during the game's most demanding moments and determines how noticeable sudden drops are. On a test rig with an RTX 4070, the settings above produced an average of 142 fps and a 1% low of 82 fps; in other words, a baseline well above 60 fps was achieved. That way, even if unexpected stutters occur mid-fight, they don't stand out.
The second critical point is upscaling technologies. If you want the best performance in Siege X, it makes more sense to keep resolution upscalers like DLSS and FSR off and find the best settings balance at native resolution. Upscaling can create ghosting, especially in fast-moving scenes, and distort the image. In a game that demands pinpoint accuracy, that kind of blur can cost you more than the frame rate you gain. That's why the recommended settings set keeps DLSS and both FSR versions off, and uses T-AA for anti-aliasing.
Recommended Siege X Settings for PC
The following combination aims to maintain a balanced image alongside high frame rate. You can apply the settings in order in the in-game menu:
- Refresh Rate: Match your monitor
- VSync: Off
- Field of View (FOV): 90
- Nvidia Reflex Low Latency: On + Boost (if supported)
- Texture Quality: Very High
- Texture VRAM Limit: Normal
- Texture Filtering: Anisotropic 16X
- LOD Quality: Ultra+
- Shading Quality: High
- Shadow Quality: Very High
- Reflection Quality: High
- VFX Quality: Ultra+
- Ambient Occlusion: SSBC+
- Lens Flare: Bloom + Lens Flare
- Zoom Depth of Field: On
- Nvidia DLSS: Off
- AMD FSR 1.0 / FSR 2.0: Off
- Anti-Aliasing: T-AA
- Adaptive Render Scaling Target FPS: 0
- Render Scaling: 100
- T-AA Sharpness: 50
The logic behind this set is: keep textures, shadows, and effects high while disabling the upscaling that blurs the image most. With VSync off, input latency drops, while matching your monitor's refresh rate keeps tearing at an acceptable level. Keeping render scaling at 100 also ensures the game is processed at native resolution; that way, the silhouette of a distant target doesn't get blurry. If your hardware can't handle these settings, don't panic; the preset logic in the next section exists exactly for that situation.
Presets, the VRAM Slider, and Weaker Hardware
Siege X offers ready-made graphics profiles: Low, Medium, High, Very High, Ultra, and Ultra+. Though they may look tempting to those seeking a shortcut, choosing a preset and saying “it'll be fine anyway” doesn't guarantee the ideal balance because of the sheer number of settings. Still, these profiles serve as a good reference point for those who don't know where to start. In tests, the difference between Low and Ultra+ was quite large; as presets went lower, frame rate could rise by up to double. This clearly shows how directly graphics settings affect performance.
If you have an older or weaker PC, it helps to know that the visual quality gap between High and Medium is noticeable. The boundary between these two levels is considered a strong starting point: dropping to Medium can deliver a serious performance gain without ruining the image too much. Also, the VRAM slider in the settings menu shows how much video memory each preset requires and how your VRAM usage changes as you toggle individual settings on and off. This tool makes it easier to find which setting creates a bottleneck, especially on graphics cards with limited video memory. In other words, instead of trial and error, you can tune by measuring; you can reduce a setting and see what you gain on screen.
Accessibility: Color Blindness, Flash Sensitivity, and Key Bindings
For a competitive game, Siege X offers a surprisingly broad accessibility menu. Chief among these are color blindness options: you can change the outlines of friendly and enemy players and the color of weapon optics according to your condition. These settings aren't just about comfort; because they directly affect how quickly you distinguish a teammate from an enemy, they also contribute to gameplay. Especially in crowded indoor fights, that kind of clarity can shorten reaction time.
The visual and audio sides have been considered too. You can change the effects created by flashbangs; this is an important convenience for people with tinnitus or sensitivity to bright white light. There's also key rebinding support and subtitle options. So you can adapt the game to both your physical and auditory needs. Such settings are also useful for reducing fatigue during long sessions; moreover, in a competitive game, it's worth remembering that comfort and performance often feed each other.
Easy Ways to Track Performance
If you want to see the effect after changing a setting, there are a few practical methods depending on your graphics card. If you use Nvidia, having the Nvidia App installed and the in-game overlay enabled is enough; the ALT + R shortcut opens the performance monitor in-game. On AMD, you can reach the same information via the Radeon overlay with CTRL + SHIFT + O. Both methods let you see the impact of setting changes on frame rate instantly; so you don't have to guess which setting actually makes a difference.
For those who want a cleaner, simpler measurement tool, there are free programs like CapFrameX or Nvidia FrameView; these work independently of graphics card brand. On handhelds, most devices have a dedicated button that lets you access real-time monitoring—also known as performance tracking—from the quick menu. Whichever method you choose, the important thing is to track the 1% low as well as the average. Because what shows you that a setting works isn't the high number in calm moments, but stability in moments of chaos.
Is an SSD Required? Test Rig and Measurement Method
One of the frequently asked questions is whether Siege X requires an SSD. Short answer: no. Whether you're targeting minimum or recommended system requirements, the game doesn't mandate an SSD. Still, switching to an SSD significantly shortens loading times and gets you into the action faster; so it's not a requirement, but a noticeable convenience. In a competitive game, shorter wait times between matches is a detail that makes a difference over back-to-back sessions.
The testing process behind these settings was carried out with a certain discipline. The rig used included an Intel Core i7-11700F processor, a 12 GB Nvidia GeForce RTX 4070 graphics card, 32 GB DDR4 3200 MHz memory in dual-channel configuration, and an MSI B560 motherboard; the operating system was Windows 11 64-bit. Tests were first run at 1920 x 1080 to determine the best settings for entry-level, then repeated at 2560 x 1440 with the same setup to measure the performance difference. Frame data was recorded with CapFrameX and sessions were compared. This approach goes beyond personal impressions like “this setting worked better for me” and provides repeatable results; you can apply the same method by setting up a similar arrangement on your own system.
Conclusion: Which Setting Should You Start With?
To sum up: on desktop PC, the best balance comes from keeping upscaling off and image clarity high while pushing frame rate as high as possible. If your hardware allows it, apply the settings list above as is; if not, the area between Medium and High stands out as the smartest starting point. Don't neglect using the VRAM slider to track which setting is straining your memory, because surprise stutters are usually caused by hitting the video memory limit. Finally, verifying setting changes by measuring each time is the most reliable habit in the long run.
On the Steam Deck side, expectations need to be set correctly from the start: due to anti-cheat incompatibility, it's impossible to run the game without installing Windows, and even then, playing with the Low preset and FSR off is the healthiest option. Windows-based devices like the ROG Ally X, MSI Claw, or Legion Go don't have such an obstacle; thanks to controller support, you can play directly in handheld mode. Whichever device you play on, regularly monitoring performance and keeping the 1% low in mind will most clearly show whether your settings are actually working.
