How to Use Upscaling & Frame Gen For Performance and Image Quality
Upscaling and frame generation can make a mid-range GPU feel high-end—or turn a crisp image into Vaseline with ghosting. This is the practical guide: DLSS, FSR, XeSS, and AFMF in plain English; Quality vs Balanced vs Performance that actually looks good; when frame gen helps and when it adds latency you’ll feel; and the exact caps and toggles that keep frametimes flat at 1080p/1440p/4K.
How to use this guide
Read the decoder to understand how each tech works. Then jump to the presets & caps for your resolution and to the game-by-game tuning playbook. Keep the artifact triage and latency checklist—those fix 90% of “DLSS/FSR looks weird” tickets.
Upscaler decoder (DLSS, FSR, XeSS) in one page
DLSS (NVIDIA): Temporal upscaler using motion vectors + neural network; quality relies on training + per-game integration. Best artifact handling overall in 2025, especially on fine detail and sub-pixel text. Works only on NVIDIA for the neural path (fallback exists but isn’t common).
FSR (AMD): Open, vendor-agnostic temporal upscaler. FSR 3.x adds frame generation and better TAAU. Image quality varies by integration; modern versions are very good in “Quality” and solid in “Balanced.”
XeSS (Intel): Temporal upscaler with an XMX (AI) path on Arc and a DP4a path on other GPUs. Quality sits between DLSS and FSR in many titles; it shines when the XMX path is used.
Takeaway: At 1440p/4K, “Quality” mode on any of the three is usually visually clean. “Balanced” is your pragmatic lever for heavier RT; “Performance” is a last resort for 4K or under-spec GPUs.
What “Quality / Balanced / Performance” actually changes
They change the internal render resolution. For 4K (3840×2160) as an example:
Quality: renders ≈ 66–67% native per axis (≈ 2560×1440) then reconstructs → best detail retention.
Balanced: ≈ 58–60% per axis (≈ 2227×1253) → good compromise at 4K with RT.
Performance: ≈ 50% per axis (≈ 1920×1080) → big perf gain, visible aliasing/ringing in fine geometry.
Internal scales vary slightly by tech/version, but the feel is the same: Quality first, Balanced when you’re VRAM/RT-limited, Performance only when you must.
Frame generation (DLSS FG, FSR 3 FG, AFMF) without the mystique
DLSS Frame Generation: interpolates motion-vector-guided frames between real renders. Big FPS boost, modest latency overhead. Best-in-class artifact handling where implemented well.
FSR 3 Frame Gen: similar concept, vendor-agnostic. Integration quality matters. Modern releases look much cleaner than early demos.
AFMF (AMD Fluid Motion Frames): driver-level frame interpolation for DX11/12 that can work in many titles, no game patch required; image stability varies with HUD/UI and camera motion.
Golden rules: (1) Don’t use FG to paper over CPU bottlenecks—if your CPU is maxed, FG won’t fix frametime spikes. (2) Always pair FG with a frame cap and VRR; the extra frames feel best when you stabilize cadence.
Latency & feel: how to keep control snappy
Cap frames 2–3 fps below panel max (or 58/116/138 for 60/120/144 Hz) using in-engine caps or RTSS. This prevents VRR overrun and input lag creep.
Prefer in-engine vs driver caps for cleaner pacing unless the engine has known issues.
Use Reflex/Anti-Lag+ equivalents only when they don’t conflict with overlays; measure feel—don’t stack three latency tools.
Turn off motion blur; it hides artifacts and adds perceived latency.
Image-quality checklist (stop the smear)
Start at Quality. If RT is heavy, step to Balanced—never jump to Performance first.
Lower sharpening to 0–20% (or the low preset). Over-sharpening highlights ringing and temporals.
Disable post-process blur/grain. These fight the upscaler.
Reduce RT reflections one notch before touching overall RT quality; reflections drive artifacts and VRAM more than shadows.
Inspect UI/HUD and thin geometry (power lines, fences) while strafing—your canary for ghosting/shimmer.
Presets & caps that just work (by resolution)
1080p (144–240 Hz esports + single-player)
Upscaler: off for esports or Quality in heavier AAA.
Frame gen: usually off for esports; on for cinematic AAA if you cap frames and accept a touch more latency.
Cap: 2–3 below panel max (e.g., 141 for 144 Hz); VRR on.
Sharpen: low. Blur/grain: off.
1440p (the sweet spot)
Upscaler:Quality by default; Balanced for heavy RT or if 1% lows drop.
Frame gen: on when GPU-limited; off if CPU-limited or in twitch shooters.
Cap: 116/138 depending on panel; VRR on.
4K (cinematic)
Upscaler:Quality; Balanced if using path-traced modes.
Frame gen: on; combine with Reflex/Anti-Lag+ and a tight cap.
Cap: 90–120 depending on game; VRR on; monitor overdrive appropriate to cap.
Game-by-game tuning playbook (applies to most modern engines)
Baseline raster: native res, RT off, establish your CPU ceiling (1080p low test pass). If you’re CPU-bound, fix that first.
Add RT (shadows → ambient → reflections in that order), watching 1% lows and VRAM use.
Turn on frame gen only if GPU-limited and frametimes are stable. Cap tightly.
Walk a busy scene: camera pans, foliage, water. Look for disocclusion ghosts and shimmer. Back off one notch if you see persistent artifacts.
Artifacts: identify and fix
Ghost trails on thin objects → lower sharpening; switch to Quality; increase TAA quality if exposed; ensure the game is feeding good motion vectors (sometimes you just need a patch).
UI/HUD smearing → enable “UI render at native” if the game offers it; reduce post-AA; some titles need HUD scale tweaks.
Shimmer in foliage → higher TAA scale or Quality upscaler; drop post sharpening; prefer anisotropic filtering 8–16×.
RT reflection crawl → lower RT reflection resolution; prefer RT shadows only; use Balanced upscaling if you must keep reflections.
VRAM pressure & upscalers (quick reality check)
Upscaling reduces internal render resolution—not texture residency. If your card is paging because of 8–10 GB limits, lower texture quality first, then pick Quality/Balanced upscaling. Frame gen adds little VRAM load; it’s a cadence tool, not a memory fix.
CPU bottlenecks & FG (don’t fight the wrong battle)
Frame gen can’t solve a pegged CPU thread feeding draw calls. Signs you’re CPU-bound: GPU util below 90% while FPS is stuck, FPS doesn’t change with resolution, 1% lows sit far below average. Fix CPU/RAM (or process clutter) first, then enable FG.
Streaming and capture (NVENC/AMF/Xe Media + FG)
Use AV1 when your platform supports it; lower bitrate, better quality.
Cap frames to free GPU headroom for the encoder; over-driving the renderer starves the media block in some titles.
Keep overlays minimal; capture and overlays can contend with the same present hooks as FG.
SFF notes (thermals amplify artifacts)
Small cases heat up post-AA and RT passes. Thermal-throttled VRAM nudges bandwidth down and exacerbates shimmer/ghost artifacts. Solution: undervolt + modest power limit; give the card a straight-shot intake; keep filters clean; prefer “Quality” upscaling for more headroom.
Testing methodology you can reproduce
Publish native vs Quality vs Balanced at fixed caps (e.g., 116 fps) with avg/1%/0.1% + a frametime plot.
Log artifacts: screenshots during strafes/pans on wire fences, foliage, and UI with motion—note settings that fix it.
Power/noise: record hotspot + noise at your cap; then undervolt 50–100 mV and show deltas.
FAQ (quick hits)
Q: Is DLSS always better than FSR/XeSS? A: No “always” in graphics—DLSS Quality is often best, but great FSR integrations can be indistinguishable in motion. Judge per game.
Q: Should I use Performance mode? A: Only if you must. It’s 1080p-ish inputs reconstructed to 4K; edges and sub-pixel text suffer.
Q: Does frame gen increase input lag? A: Slightly, yes. With Reflex/Anti-Lag+ and a tight cap, most single-player feels great; esports usually keep FG off.
Q: My HUD is smeared with FG on—broken? A: Some titles need “UI at native res” toggles or patches. Try lower sharpening and ensure TAA isn’t at a “low” preset.
Bottom line
Upscaling and frame gen are tools—not magic. Use Quality at 1440p/4K, drop to Balanced for heavy RT, cap frames tightly with VRR, and keep sharpening low. Turn FG on when the GPU—not the CPU—is the limiter. Do that, and a value 12–16 GB card will feel buttery where it counts: in the frametime graph, not just the average FPS number.
