RDR2's PC version has a remarkably large amount of settings which the user can tweak. Here we will list what each does, as well as the impact that they can have on each user’s frame rate and performance. Please be aware that the listed FPS benefits are not perfectly additive; if one setting drops FPS by 10% and another drops it by 5%, disabling both may provide ~12% better FPS rather than 15%.
It is worth noting that the default settings for even powerful PCs in Red Dead Redemption II is High, not Ultra. The Ultra settings are reserved for those with seriously incredible builds. To give a little bit of context, my gaming rig runs an i7-8700K at 4.9GHz with a GTX 1080 Ti; at 1440p with Ultra settings, this was the benchmark result:
It's not the end of the world, though. If you tweak your settings a touch, you can get something a little more sensible. This next benchmark was taken at 1080p on a system with an R5 3600 and an RX 5700 XT:
The settings below are split into 2 sections. This is because, by default, Rockstar locks out a section of graphics. As such, we normally advise only touching these if you absolutely have to do so.
RDR2 Basic Settings
Texture Quality
Texture Quality affects the amount of detail that is shown on each model. This is very VRAM-intensive. There is a large difference between the highest and lowest settings, so if you are planning on using the “high” setting then it is a good idea to have a card with a minimum of 4GB of VRAM. One of the most noticeable differences between the settings, as demonstrated in the screenshots, is a flattening and serious simplification of the textures in the world.
Note: if you're changing this setting, it's one of the few that requires a game restart to take effect (which impeded our ability to get reliable comparative performance stats for it).

Global Illumination
An overall lighting setting that runs in tandem with a lot of the other sub-sections below. Think of it like that line in the Lion King, "Everything that the light touches..." But that's also why this setting can get frustrating. If you're indoors (at least generally) there's less going on, so illumination being lower or higher isn't a problem. Yet if we add in the Sun, some fire, lights and a challenging lighting environment, it can be very, very unforgiving on Ultra.
In the screenshots below, pay attention to the specks of light coming off the snow just over the right shoulder, as well as the softer light in the background overall.
Performance impact: ~10% between Low and Ultra

Anti-aliasing
Anti-aliasing is meant to smooth out the jagged edges of objects in 3D graphics images. To be slightly more specific, it is typical to see the edges of objects looking rough in-game because the screen is using pixels to simulate straight lines that aren't perpendicular to the sides of the monitor. Anti-aliasing helps to smooth these out, usually by softening and blending the colors around these angled lines, making them appear less pixelated than they otherwise would.
FXAA
FXAA, also known as Fast Approximate Anti-Aliasing, is a form of anti-aliasing that does not require a ton of computational power. There is no increase in VRAM usage with this setting on, although it does create a slight frame rate hit (about a 5% change in FPS). The reason this doesn’t have a huge performance hit is because this form of AA smooths the appearance of models based on how they appear on the screen, rather than doing an analysis of the models themselves. With this setting enabled you can expect to see slightly smoother-looking models, and the edges of objects should look more realistic.
Where this actually is quite noticeable is in the snow detail for you earlier on in the game. If you have this set to a lower mode, you'll notice a lot of pop-in effects happening with the footprints and horse tracks. In the screenshots below, pay attention to the simplification on the tracks the further you look from the character.
Performance impact: ~5% between Off and On

MSAA
Multisample Anti-Aliasing renders the game at a higher resolution before then proceeding to downscale it to the resolution of your monitor. This leads to a much crisper image, but it does sacrifice performance in the process. This is a very systematically demanding setting that requires a lot of VRAM to work properly. Using high-level MSAA is sure to cause a change in performance, but the results can be very pretty.
Performance impact: ~50% between Off and Max Settings (higher cost at higher resolutions)
Shadows
These settings affect the presence and quality of visible shadows on objects and entities in-game.
Shadow Quality
This setting is the one that is most important when it comes to the visual fidelity of the game’s shadows. It affects the accuracy of the shadows presented, along with the resolution and definition seen in said shadows.
A lot of the game's shadows are impacted by the overall lighting quality too, so you'll notice this far more in the bright sunlight outdoors versus the darker interiors.
Performance impact: ~10% between Low and Ultra
Drag the bar to compare Shadow Quality on Low and Ultra.
Far Shadow Quality
A follow-on from the above setting, that specifically impacts shadows being rendered at a distance. Like the above, this can have a huge impact depending on where you are in the world.
Performance impact: ~7% between Low and Ultra
Reflection Quality
This setting improves the reflections found on all surfaces in the game. This is noticeable on vehicles, windows, water, and other shiny surfaces such as the occasional wall or floor. This is especially noticeable in the game when it is raining.
Performance impact: ~18% between Low and Ultra
Mirror Quality
This impacts reflections in mirrored surfaces, like a more specific version of the setting above. If it's just your ugly mug in a mirror, then it's a low impact. If there's a lot of mirrored surfaces, it's greater.
Performance impact: ~5% between Low and Ultra
Water Quality
Water quality is a graphical setting that is extremely important to making the game look as visually impressive as possible. As you might imagine with such a variety of environments, any water elements can impact the overall visuals of each area.
What effectively happens here is a drop-off in water reflections and smatterings of light on the water's surface. However, you can only see this if you're up close, as you can see with the low-down shots here.
Performance impact: ~8% between Low and High
Drag the bar to compare Water Quality on Low and High.
RDR2 Advanced Settings
A lot of these setting exist for users who want to tweak the graphics further than the above options. So rather than having a simplistic "change main graphics from option x to option y" it's more like "change one graphics setting with options 1, 2, and 3 each from high, medium, or low".
Nevertheless, we've done our best to determine the impact difference between 'all the way on' and 'all of the way off' for each of them to the best of our ability. But many of these options are also quite visually subtle or only visible in-motion, so we've omitted descriptions and screenshots for a number of them.
Particle Lighting Quality
This setting mainly affects explosions, which are randomized to begin with. Even ignoring outside factors such as physics, weather, and location, it is hard to get a solid baseline of comparison. It has little FPS impact unless you get into a really nasty fight with a LOT going on.
Performance impact: ~2% between Low and Ultra
Advanced Shadow Options
These three settings govern more granular control over the appearance and scope of shadows in the game.
Long Shadows
This setting is made to render more accurate environments during the game’s dusk and dawn, along with slightly increasing the shadow quality overall. It is a very difficult setting to notice, even in a side-by-side comparison. It does not cause a particularly noticeable performance hit in terms of frame rate or VRAM usage.
Performance impact: Negligible between Off and On
Grass Shadows
When character shadows are not enough, your blades of grass need shadows. Although visually impressive in the open areas, if your system isn't up for it, all the additional rendering can cause problems.
Performance impact: ~8% between Low and High
Soft Shadows
Soft Shadows is a setting that aims to make the game look more realistic. Light has a tendency to leave soft edges on shadows in real life, and this setting makes it look similarly in the game. If you have a lot of light sources, be warned that this can lean heavily on hardware if using the higher options here.
As you'll see from this shot comparison, it's only around the softer edges of light that you can typically see the impact of soft shadows, but even then it is slight. Again, a lot of this tends to make things look more flat, rather than realistic. Plus, on a single main light source, it really has very little impact to the overall experience.
Performance impact: ~7% between Low and Ultra
Drag the bar to compare Soft Shadows on Low and Ultra.
Advanced Water Options
These 3 settings run more or less in tandem with the main Water Quality setting in the normal options. Rule of thumb here: don't run these on higher options if you have the main control on Low. There's no point.
As you can move each of these independently, if you're looking to save yourself some frames, the main one to pull lower first is water physics. Although this means you don't get as fine a splash when you ride through water, for instance, it has a far bigger performance gain for a lower visual impact.
Water Refraction Quality
Performance impact: ~3% between Low and High
Water Reflection Quality
Performance impact: ~3% between Low and High
Water Physics Quality
Performance impact: ~6% between Low and Full
Drag the bar to compare Custom Water Settings on Low and High.
Advanced World Detail Options
Although not specifically labelled as such, these options all link into what you have set for Texture Quality and the various AA options. Like the above with the water, there's no point having these set to a high level if you have Textures and AA set to Low.
Geometry LoD
Performance impact: ~12% between Lowest and Highest
Grass LoD
Performance impact: ~7% between Lowest and Highest
Tree Quality
Performance impact: ~5-15% between Low and Ultra (very environment-dependent)
Decal Quality
Performance impact: ~5% between Low and Ultra
Fur Quality
Performance impact: ~4% between Lowest and Highest
