Summary of "Nvidia BEST Settings are now so EASY HUGE Nvidia Update"

Overview

NVIDIA released DLSS 4.5. The new system dynamically selects between DLSS 4 and DLSS 4.5 depending on the chosen quality preset to balance visual fidelity and performance.

DLSS 4 is generally faster.
DLSS 4.5 produces better visuals but is heavier to run and is optimized primarily for RTX 4000/5000-series GPUs.
Older cards (RTX 20/30-series and lower-end 40-series) may see worse performance with DLSS 4.5.
Minimum driver required: 591.74 — update drivers if DLSS 4.5 does not appear.

Quick setup (step-by-step)

Open the NVIDIA app (system tray or Start menu).
Go to Settings → About and opt into early access/beta/experimental features to receive updates quickly.
Drivers → Check for updates and install if available (minimum: 591.74).
Graphics → choose Global Settings (or Program Settings for per-game overrides).
Set “DLSS override model presets” to Recommended (formerly “Latest”) and Apply.
- This enables DLSS 4.5 where applicable automatically.

How DLSS presets map to versions (observed behavior)

Preset K = DLSS 4
Presets M and L = DLSS 4.5

In-game DLSS quality choices (general observations):

Quality or Balanced → usually uses DLSS 4 (faster).
Performance or Ultra Performance → usually uses DLSS 4.5 (better visuals, heavier).

Always measure actual FPS across presets—sometimes DLSS 4.5 performance modes can be slower than DLSS 4 quality modes.

Practical recommendations

If you prioritize FPS or are on RTX 20/30-series or lower-end 40-series GPUs: default to DLSS 4 (Quality/Balanced or force preset K) for better frame rates.
If you have higher-end 4000/5000-series GPUs and want visual fidelity: try Performance/Ultra Performance (DLSS 4.5) but verify FPS impact.
Test multiple modes per game and resolution (for example, 4K) before settling on a preset.

How to force DLSS 4 across presets (override)

In the NVIDIA app:
- DLSS override model presets → change from Recommended to Custom.
- Under Super Resolution choose Recommended (manual) → pick preset K (DLSS 4) → Apply.
You can set this globally or per-game via Program Settings.

In-game diagnostics & overlays

Enable NVIDIA overlay: NVIDIA app → Settings (cog) → Features → NVIDIA Overlay → enable. Use Alt+Z to open the overlay.
HUD stats: Overlay → Statistics → enable heads-up display and select DLSS to show version/preset/resolution scaling in-game.
Advanced indicator (registry tweak): the video shows editing HKEY_LOCAL_MACHINE → Software → NVIDIA Corporation → Global → NGX Core and adding a DWORD (named something like “show DLSS indicator”) with a numeric value to enable a detailed DLSS overlay.

Note: The subtitle’s exact registry key/value (and number shown) may contain transcription errors — confirm the exact key/value from NVIDIA or reliable documentation before editing the registry.

Observed in-game examples / behavior

Example from the video (Arc Raiders): running at 4K with Ultra Performance showed native render at 720p with motion artifacts visible. It can look good for slower-paced scenes but exhibits artifacts at distance or during movement.
The guide emphasizes testing visuals and FPS trade-offs per game.

Cautions

DLSS 4.5 can be significantly heavier on older GPUs — don’t assume it will always boost FPS.

Registry edits can be risky; double-check the exact keys/values before changing them.

Update drivers first (minimum driver: 591.74) if DLSS 4.5 does not appear.
