NVIDIA’s March 25, 2025 NVIDIA App update added four substantial pieces of functionality: the experimental local AI assistant Project G-Assist, per-game DLSS overrides with a custom 33%–100% render scale, and Control Panel display-scaling and color tools. The headline update is historical, but G-Assist’s supported hardware and software requirements have since changed, so launch specifications and current compatibility should be treated separately.
What the update adds
| Feature | What it does | Best for |
|---|---|---|
| Project G-Assist | Uses a local small language model to control supported NVIDIA and third-party PC functions through text or voice. | RTX owners who want guided tuning and diagnostics. |
| Custom DLSS scaling | Sets DLSS Super Resolution’s input render scale anywhere from 33% to 100%. | Players fine-tuning image quality and frame rate. |
| DLSS overrides | Offers driver-level model and mode overrides, including newer Frame Generation and Transformer options where supported. | Games with compatible DLSS implementations. |
| Display Scaling | Moves GPU, monitor and integer-scaling controls into the NVIDIA App. | Users migrating display settings from Control Panel. |
| Display Color | Provides color-depth, contrast, gamma and calibration controls. | Users tuning a display through the GPU. |
Details of the original release are documented in NVIDIA’s March 2025 announcement.
Project G-Assist: a local gaming and system assistant
Project G-Assist is an experimental assistant for compatible GeForce RTX PCs. NVIDIA says its small language model runs locally on the RTX GPU rather than sending ordinary requests to a general cloud chatbot. You can type requests or, on supported hardware, speak them. The assistant calls defined NVIDIA and third-party APIs to perform supported actions; it is not an autonomous game-playing agent or a universal PC administrator.

Depending on the installed version, G-Assist can optimize game settings, apply DLSS overrides, change Low Latency Mode or Smooth Motion, enable RTX HDR or Digital Vibrance, display hardware temperatures and performance statistics, capture screenshots, and adjust selected encoder, lighting, fan, monitor or peripheral settings. Plug-ins expand that list, but may require companion software, SDK permissions, accounts, firmware or compatible hardware.
#1 Best Overall
- AI Performance: 767 AI TOPS
- OC mode: 2632 MHz (OC mode)/ 2602 MHz (Default mode)
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure
- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis
NVIDIA labels G-Assist experimental and warns that recommendations or actions can be inaccurate. Graphics changes may require restarting a game. Local processing also temporarily uses GPU resources, which can affect response time or game performance while a request is being handled. “Local” should not be read as a guarantee that every plug-in is independent of other applications or services.
How to install and launch it
- Open the NVIDIA App and select Home.
- Open Discover and install Project G-Assist (labels can move in newer app versions).
- Launch it from the NVIDIA App overlay, or use Alt+G when the shortcut is available.
Examples of useful requests include “Optimize my graphics for Cyberpunk 2077,” “Show my GPU temperature,” “Turn on Low Latency Mode,” or “Set my video encoder codec to AV1.” These are examples of supported-function requests, not a promise that every command works on every system or game.
Launch requirements versus current requirements
The March 2025 release required Windows 10 or 11, a desktop GeForce RTX 30-, 40- or 50-series GPU with at least 12GB of VRAM, driver 572.83 or newer, roughly 6.5GB for the System Assistant and another 3GB for voice commands. English was the listed language.
Rank #2
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Powered by GeForce RTX 5060
- Integrated with 8GB GDDR7 128bit memory interface
- PCIe 5.0
- WINDFORCE cooling system
NVIDIA’s current G-Assist documentation is broader: Windows 10/11, an RTX 20-, 30-, 40- or 50-series desktop or laptop GPU with at least 6GB of VRAM (or an equivalent RTX PRO card), NVIDIA App 11.0.7 or newer, and driver 580.97 or newer. It lists approximately 7GB for the System Assistant and 3GB for voice commands. Voice input is limited to RTX 30-series and newer. NVIDIA recommends about 6GB of free VRAM for Reasoning Mode or 4.5GB for Flash Mode when another game or application is running. Check that page before troubleshooting an installation, because requirements are version-sensitive.
Custom DLSS scaling explained
The update adds a Custom choice under the driver’s DLSS Super Resolution override. Instead of being restricted to named presets, you enter an input-resolution percentage from 33% to 100%. That percentage controls the internal render resolution that DLSS reconstructs; it does not arbitrarily change your monitor’s output resolution.
| Mode | Approximate input scale |
|---|---|
| DLAA | 100% |
| Quality | 67% |
| Performance | 50% |
| Ultra Performance | 33% |
For example, 40% can deliver more performance than the usual Performance setting while retaining more input detail than Ultra Performance. A value between Quality and DLAA can be useful on a high-resolution monitor when you want extra frames without dropping to a standard preset.
Rank #3
- Powered by the NVIDIA Blackwell architecture and DLSS 4
- Powered by GeForce RTX 5070 Ti
- Integrated with 16GB GDDR7 256bit memory interface
- PCIe 5.0
- WINDFORCE cooling system
Where to set it
- Open Graphics in the NVIDIA App.
- Select Program Settings and choose the game or application.
- Open Driver Settings.
- Find DLSS Override – Super Resolution.
- Choose Custom and enter a value from 33% through 100%.
The title must support the relevant DLSS path and driver override. This setting cannot add DLSS to a game that has no compatible DLSS implementation. Lowering the scale usually reduces fine detail and can increase shimmering, ghosting or other temporal artifacts. Results vary with resolution, motion, ray tracing, engine and the game’s DLSS integration. It is a tuning control, not a guaranteed frame-rate percentage.

Other DLSS overrides
- DLSS Multi Frame Generation Override: for RTX 50-series systems when Frame Generation is enabled in the game. Multi Frame Generation is not an RTX-wide feature.
- DLSS Frame Generation Model Upgrade: for RTX 40- and 50-series users with Frame Generation enabled.
- DLSS Transformer Model Upgrade: applies the Transformer model to Super Resolution, Ray Reconstruction or DLAA on supported RTX hardware.
- DLAA and Ultra Performance: exposes those modes in compatible games that do not provide a native in-game selection.
These functions are distinct. Super Resolution reconstructs an image from a lower-resolution input; DLAA uses native-resolution input for anti-aliasing; Ray Reconstruction targets ray-traced reconstruction; Frame Generation creates additional displayed frames. Frame Generation still benefits from a sensible base frame rate and can introduce latency or visual artifacts.
Display Scaling and Display Color move into the app
Under the launch-era path System > Displays, NVIDIA added controls that had traditionally lived in NVIDIA Control Panel.
Rank #4
- Powered by the NVIDIA Blackwell architecture and DLSS 4 OC mode: 2640MHz/Default mode: 2610MHz (Boost Clock)
- Military-grade components deliver rock-solid power and longer lifespan for ultimate durability
- Protective PCB coating helps protect against short circuits caused by moisture, dust, or debris
- 3.125-slot design with massive fin array optimized for airflow from three Axial-tech fans
- Phase-change GPU thermal pad helps ensure optimal thermal performance and longevity, outlasting traditional thermal paste for graphics cards under heavy loads
Display Scaling lets you choose scaling modes and whether the GPU or monitor performs scaling. Hardware-accelerated integer scaling is useful for pixel-art games because it preserves crisp, hard-edged pixels. It can also produce borders or fail to fill the screen cleanly when the source and output resolutions are not an exact integer multiple.
Display Color exposes color depth, contrast, gamma and advanced calibration options, including GPU-side overrides of display defaults. This is primarily a migration and consolidation improvement, not an entirely new display technology. NVIDIA has continued moving Control Panel functions, but the App does not necessarily replace every Control Panel option.
Compatibility details that are easy to confuse
“RTX support” is not one universal compatibility label. G-Assist’s current 6GB requirement differs from its 12GB desktop-only launch requirement. Voice commands require RTX 30-series or newer. Transformer, Frame Generation and Multi Frame Generation each have their own generation and game requirements. Display Scaling does not require DLSS, and monitor controls in G-Assist are limited in NVIDIA’s documentation to G-SYNC desktop monitors—not every G-SYNC Compatible or variable-refresh display.

Should you install the update?
It is a worthwhile update for RTX owners who want centralized per-game controls, finer DLSS tuning or an easier route to settings that were formerly split between the NVIDIA App and Control Panel. Custom scaling is the most immediately practical addition: it lets you tune around a GPU bottleneck or refresh-rate target instead of jumping between four fixed presets.
G-Assist is more experimental. It can help newcomers find settings and can automate supported actions, but users who need predictable, manual configuration should verify every change. Non-RTX owners cannot use the RTX-dependent AI features, and buying a new GPU solely for G-Assist is difficult to justify without considering resolution, ray tracing, VRAM and the games you actually play.
Troubleshooting
- Install a current Game Ready or Studio driver that meets the feature’s documented minimum.
- Restart the game after changing a driver override; some settings apply only at launch.
- Confirm the game is using DLSS Super Resolution, Frame Generation or the specific feature you are overriding.
- If image quality is poor or the game behaves unexpectedly, return the override to its default, or disable it under Graphics > Program Settings.
- For G-Assist, check the requested setting manually and use its feedback or issue-reporting control when an action fails.
- For a peripheral plug-in, verify the companion application, SDK permission, firmware, account and device compatibility.
For evolving requirements and later additions such as Flash Mode, G-SYNC controls and community plug-ins, consult NVIDIA’s NVIDIA App release highlights and the current G-Assist page.
The Bottom Line
The update combines a genuinely useful DLSS fine-tuning control with a broader migration of display settings and an ambitious—but still experimental—local AI assistant. Install it if you already have compatible RTX hardware and want these controls; treat G-Assist and driver overrides as tools to verify, not automatic fixes.
