Anti-Aliasing Modes Ranked: FXAA vs TAA vs MSAA — What Each Costs in FPS

Anti-aliasing is one of the most misunderstood settings in any graphics menu. Most guides tell you FXAA is cheap and MSAA is expensive — but not how expensive, not why MSAA barely works in modern games anymore, and not which mode you should actually choose based on what GPU you own. This guide fixes that. New to graphics settings generally? Our game settings explained guide covers the full picture before you dive in.

Why Jaggies Exist — and What AA Actually Does

Every display is a grid of square pixels. When a game renders a diagonal line — the edge of a wall, a character’s arm, a rifle barrel — the renderer approximates that smooth curve using those squares. The result is the stair-step pattern called aliasing, or “jaggies.”

Anti-aliasing fixes this by blending the edge pixels with their neighbors to make the transition appear smoother. The different methods disagree on when and how to do that blending — which is why they have completely different performance costs and visual trade-offs. Two broad approaches exist: supersampling (render more pixels than you need, then shrink down) and algorithmic guessing (analyze nearby pixels to infer where smooth edges should be).

FPS Cost Per Mode — The Numbers Competitors Don’t Give You

Approximate impact at 1080p across modern titles. Your actual result depends on game engine, scene complexity, and GPU generation [3].

Every Mode Explained

FXAA — Cheapest, Softest

FXAA runs as a post-process pass after rendering completes — it doesn’t touch the 3D pipeline at all, just scans the final image for high-contrast edges and blurs them. That’s why it costs only 2–7% FPS: it’s essentially an image filter applied to a screenshot, not a rendering technique.

The trade-off is softness. Because FXAA blends pixels across the whole image rather than targeting only 3D geometry edges, it can blur HUD text, fine textures, and distant detail alongside the jaggies it’s meant to fix. In competitive shooters where spotting an enemy at 200 meters matters, this is a real problem. For slower-paced games where image cleanliness matters more than sharpness, it’s a reasonable choice on budget hardware.

SMAA — Almost Free, Noticeably Sharper

SMAA (Subpixel Morphological Anti-Aliasing) pairs edge detection with morphological analysis — it identifies edges like FXAA does, but also evaluates the shape of each edge before blending, producing sharper results on geometry without the full-image blurring. Performance cost: 3–8%, nearly identical to FXAA.

If your game offers both FXAA and SMAA, pick SMAA every time. The image stays noticeably sharper at roughly the same FPS hit. It’s the best value option when DLSS, FSR, or XeSS aren’t available.

TAA — Industry Standard, With a Ghosting Problem You Can Fix

TAA is the default in virtually every modern game built on Unreal Engine 4/5, Unity HDRP, or id Tech 7. It samples different sub-pixel positions across consecutive frames and blends them using a velocity buffer — a per-pixel map of where each object moved between frames. This gives it excellent edge coverage at roughly 8–15% FPS cost, and it handles transparent geometry, vegetation shimmer, and thin objects that break FXAA entirely.

The ghosting comes from a specific failure in that velocity buffer. When a fast-moving object passes over background pixels, those pixels go from being covered to uncovered between frames. TAA tries to reproject them using the velocity buffer anyway, and when reprojection fails on those newly exposed pixels, it falls back on stale color data from the previous frame position — the object appears to smear or ghost as it moves.

Quick fix: Most games that force TAA expose a Sharpness or Clarity slider in graphics settings. Set it to 50–75% to recover texture detail without reintroducing jaggies. In Unreal Engine games with a console, the command r.Tonemapper.Sharpen 0.5 does the same. This is a developer-acknowledged workaround — the blur is not a display problem, it’s inherent to the temporal blending algorithm [1].

MSAA — Sharp Image, Mostly Dead in Modern Games

MSAA produces the sharpest anti-aliased image of any traditional method. A 4x pass renders each geometry edge fragment four times at offset sub-pixel positions, then averages them — clean, noise-free edges while leaving textures fully intact. In older titles and racing sims that still offer it, 4x MSAA is visually excellent.

The problem is architectural. MSAA requires forward rendering, where the pixel shader runs on each fragment sample before lighting is applied. Modern game engines use deferred rendering: all geometry data is written to a G-buffer first (normals, albedo, depth), and lighting is computed in a separate pass using that buffer. By the time the lighting shader runs, the per-sample data MSAA needs has already been discarded — the technique can’t function as designed in a deferred pipeline.

This is why most post-2015 open-world and UE4/5 titles don’t offer MSAA, or only expose it for transparency and foliage edges. Where you will still see it: Source engine games (CS2, TF2), older racing titles (Assetto Corsa), and a few forward-rendered indies. On those, 4x MSAA is a valid choice if your GPU can handle the cost.

SSAA — Maximum Quality, Only for Screenshots

SSAA renders your entire scene at 2x or 4x the target resolution, then downsamples to your display size. At 2x, you’re rendering four times as many pixels as your screen can show — hence the 50–75% FPS hit [3]. The image quality is unmatched because every pixel is computed at full detail, but the only practical use cases are screenshot capture and cutscene recording. If you see SSAA in a graphics menu and your GPU isn’t a 4090 or equivalent, ignore it.

Which Mode Should You Actually Use?

For a broader look at which settings have the biggest FPS impact across your whole setup, see our PC optimization guide.

DLSS, FSR, and XeSS: The Modes That Add FPS Instead of Cutting It

Traditional anti-aliasing trades FPS for smoother edges. DLSS, FSR, and XeSS invert that equation — they render at a lower internal resolution and use machine learning or spatial algorithms to reconstruct a higher-resolution output. Anti-aliasing happens as part of that reconstruction pass, which is why they replace traditional AA entirely rather than stacking on top of it.

At Quality preset, all three deliver 30–50% FPS gains over native rendering with anti-aliasing included [4]. The choice between them comes down to your GPU:

• DLSS (RTX 20-series or newer): Tensor Core-based, highest image quality, DLSS 4 multi-frame generation reserved for RTX 50-series
• FSR 3 (any GPU): Open-source, works on NVIDIA, AMD, and Intel hardware — broad support across titles released in 2023+
• FSR 4 (RX 9000-series only): Machine-learning FSR exclusive to AMD’s 2025 GPUs, significantly sharper than FSR 3 [5]
• XeSS (Intel Arc AI mode, DP4a fallback): AI mode gives best quality on Arc; shader-based fallback still outperforms FXAA on non-Intel GPUs

Important: Set in-game AA to Off when any upscaler is active. Upscalers include a temporal AA pass internally — running FXAA or TAA on top double-blurs the already-reconstructed output. Most games enforce this automatically; some don’t.

Frequently Asked Questions

Does turning off anti-aliasing give a significant FPS boost?

At 1080p, yes. Switching from TAA to Off typically recovers 8–15% FPS, and from MSAA 4x to Off can recover 20–40% [3]. At 1440p or 4K, the gain is proportionally similar but the visual downside is smaller — higher pixel density already reduces jaggies naturally, so disabling AA is often the right call for competitive play at those resolutions.

Why is TAA blurry in some games but perfectly sharp in others?

Implementation quality, not the algorithm. A well-tuned TAA pass (Cyberpunk 2077, Red Dead Redemption 2, Microsoft Flight Simulator) pairs reprojection with an aggressive sharpening pass and carefully tuned jitter patterns. A rushed implementation — common in UE5 projects that ship with default TAA settings — blends frames without compensating for blur. In both cases, enabling the in-game sharpness slider at 50–75% recovers most of the lost detail. If there’s no slider, r.Tonemapper.Sharpen 0.5 in the console works on any UE game.

Does anti-aliasing affect GPU or CPU performance?

Primarily GPU. FXAA, SMAA, and TAA run as GPU post-process passes after the main render, with negligible CPU overhead. MSAA has higher GPU memory bandwidth cost because it stores multiple samples per pixel in the framebuffer. DLSS and FSR add a small GPU inference pass but the FPS gain from rendering at lower resolution more than compensates. On CPU-bound systems where the GPU is waiting for draw calls, AA cost may appear lower than expected — the GPU has idle time to fill.
