For R6 Siege best settings on PC, the three options that move FPS the most are resolution, the quality options and V-Sync, and each one points the same way: lower it or turn it off. Before touching them, open Options > Graphics and make sure the Video Memory bar at the top is not over your graphics memory limit. This guide is current as of September 30, 2026, uses only the direction that Ubisoft support describes, and covers PC only because console menus differ. It gives no exact per-option numbers because there is no official basis for them; if recording is what makes your frame rate drop, see fixing FPS drops while recording instead.
Bottom line: lower resolution, quality and V-Sync
Lowering resolution can often free up some frame-rate headroom, but it can blur distant enemies, and turning V-Sync off removes the frame cap at the cost of possible screen tearing. Either way, it is safer to check the result after each change than to drop everything to the minimum at once. If the game feels sluggish even at a good frame rate, reducing input lag is worth checking as well. If the Video Memory bar is already at its limit, fix that before anything else.
Order to apply the changes
- 1Pick a scene to compare — Choose one map and one spot where your frame rate felt worst, and write down what it is now. Without a baseline you cannot tell whether a change actually helped.
- 2Open Options > Graphics — Go to Options > Graphics in the game and look at the Video Memory bar at the top. If your current setup is over the graphics memory limit, watch whether the bar shrinks in the steps that follow.
- 3Lower resolution by one step — Drop resolution by a single step and compare frame rate and sharpness in your scene. If frames are high enough, stop there; if distant enemies became hard to read, go back one step.
- 4Lower the quality options gradually — Reduce the quality options one or two at a time instead of all at once. No official per-item values could be confirmed, so none are given here; your own frame rate and how easily you spot enemies are the yardstick.
- 5Turn V-Sync off and check for tearing — Switch V-Sync off and watch how the frame rate changes in the same scene. If tearing bothers you, turn it back on and find headroom in the other options.
- 6Confirm in a real match — Play one real match rather than a practice scene and note where frames dip or the picture feels cramped. If you also run recording or a voice app, test with them running.
Option-by-option direction
| Option | What it does and which way to go | Basis |
|---|---|---|
| Resolution | Sets how many pixels are drawn. Lower gives more frame rate headroom, but too low blurs distant enemies. | Ubisoft support says lowering resolution can help FPS |
| Quality options | Sets the quality of the detailed effects that make up the image. Lower gives more headroom, and a simpler image can make enemies easier to pick out. | Ubisoft support says to lower quality (no per-item values) |
| V-Sync | Locks frames to the monitor refresh rate. Turning it off lifts the cap, but tearing can appear, so compare it yourself. | Ubisoft support says turning V-Sync off can help |
| Video Memory bar | Shows graphics memory use as you change options. Going over the limit can cause performance problems, so stay inside it. | Ubisoft support Video Memory guidance |
| Load outside the game | Recording and overlays use the same PC resources. Recheck with those programs running once your options are set. | General PC resource principle (no official figures) |
Checklist after applying
- I wrote down the frame rate of my scene before changing anything.
- The Video Memory bar stays within the limit.
- Distant enemies are still readable after lowering resolution.
- I changed the quality options one or two at a time and compared.
- I checked whether screen tearing is tolerable with V-Sync off.
- Frame rate holds up with recording or voice apps running.
When you record Siege at the same time
Once your settings have bought you some headroom, the next question is whether you can leave recording on. DOR is a free Windows desktop app, and Siege is a supported game, so it detects the match automatically and saves the full match as an mp4; Siege does not get automatic highlight clips, so the moments you want to keep have to be picked out by hand. On an NVIDIA graphics card, NVENC hardware encoding is the default, which hands the encoding work to the graphics card, and it captures game sound and your microphone together so you can replay what you heard in the match and your own voice later. From the in-app library you can set a start and end with the trim tool and share a dor.gg link, or tidy the length in DOR Studio in your browser with nothing to install. For game info see the Rainbow Six Siege hub, and for how to keep round moments see saving Rainbow Six clutch clips.
Official sources and how to check
Checked as of September 30, 2026. Option names and screen layout can change with patches, so treat the in-game Options > Graphics screen as the final reference.
