GPU Optimization Guide: Nvidia and AMD Settings for Max FPS

Most players never touch NVIDIA Control Panel or AMD Radeon Software after installing their GPU drivers. That's a mistake. The default settings are tuned for general use — they actively cap your GPU's clock speed to save power and pre-render frames to smooth output. For gaming, those tradeoffs cost you FPS and input lag you don't need to give up.

Here's exactly what to change, and why each setting matters.

NVIDIA Control Panel Settings

Right-click desktop → NVIDIA Control Panel, or find it in the Start menu.

Manage 3D Settings → Global Settings

Power management mode: Change from "Optimal power" to Prefer maximum performance. The default mode reduces GPU clocks during brief load dips between frames, causing clock ramp-up latency that shows up as microstutter. Maximum performance keeps clocks high at all times.

Low Latency Mode: Set to Ultra. This reduces the GPU render queue to minimum. Your CPU submits fewer frames in advance, which increases GPU utilization slightly but dramatically reduces system latency. Measurable in frame timing tools as 10–30ms latency reduction.

Max Frame Rate: Leave at Off unless you have a specific reason to cap (like using G-Sync at maximum monitor refresh). Let the game or NVIDIA Reflex handle frame pacing.

Texture filtering - Quality: Set to High Performance. Anisotropic filtering is handled better in-game anyway. The driver-level quality setting mostly affects edge cases that aren't visible during gameplay.

Vertical sync (in NVIDIA Control Panel): Set to Off. If you use G-Sync, set it to "Use the 3D application setting" and disable V-Sync in-game.

Shader Cache Size: Set to Unlimited or a large fixed value (10GB+). This allows DirectX 12 and Vulkan games to cache compiled shaders without eviction, eliminating shader compilation stutter after the first session.

Configure Surround, PhysX → PhysX Configuration

Set PhysX processor to your dedicated GPU, not Auto. On Auto, Windows can use the CPU for PhysX in some scenarios — less efficient.

Display → Adjust desktop size and position

If you play at a different resolution than native: set Scaling to Display (not GPU) for no scaling overhead. Set Full-screen mode to let games that request native fullscreen bypass the scaler.

NVIDIA Resizable BAR (ReBAR)

Resizable BAR allows the CPU to access the full VRAM (instead of 256MB chunks). On RTX 30/40 cards with supported motherboards, it's free FPS.

Check status: NVIDIA Control Panel → Resizable BAR → should show "Supported / Enabled".

To enable if it's off:

1. Update motherboard BIOS to the latest version (most boards added ReBAR support in 2021+ updates)
2. BIOS → Above 4G Decoding → Enable
3. BIOS → Resizable BAR or Re-Size BAR Support → Enable

Games with confirmed ReBAR gains: Elden Ring (+10%), Far Cry series (+8%), Cyberpunk 2077 (+6%), Assassin's Creed games (+5%).

AMD Radeon Software Settings

Open Radeon Software (right-click desktop → AMD Software: Adrenalin Edition) or from the Start menu.

Performance → Tuning

Tuning Control: Manual Power Tuning: Slide TDP (Power Limit) to 0% or slightly positive. This ensures the GPU runs at full power during gaming. Negative values reduce power to lower heat/noise at cost of performance.

GPU Frequency: Leave on Automatic unless you're manually overclocking. Radeon's auto-OC algorithm is generally good.

Gaming → Graphics

Radeon Anti-Lag: Enabled. AMD's equivalent of NVIDIA's Low Latency Mode. Reduces input latency by limiting the render queue.

Radeon Anti-Lag+: Available on newer drivers for supported games. More aggressive than standard Anti-Lag. Enable if available for your game.

Image Sharpening (RIS): Set to 80% sharpening if you play at a lower resolution. It compensates for the blurriness of upscaling. Leave off at native resolution.

Wait for Vertical Refresh: Set to Off (same as disabling V-Sync globally).

Radeon Boost: Dynamically reduces resolution during fast movement, increasing FPS at minimal visual cost. Worth testing — works well in competitive games where you're already moving fast and not scrutinizing pixels.

AMD FidelityFX Super Resolution (FSR)

If your games support FSR, use it at Quality mode for 77% render resolution with significant FPS gains. FSR works on any GPU (not just AMD) and doesn't require driver integration.

FSR 3 with Frame Generation (supported in select titles) can double frame rates from a base rendered frame. It adds some latency but works on older hardware unlike DLSS Frame Generation.

NVIDIA DLSS

For NVIDIA RTX users, DLSS Quality mode renders at ~67% resolution and upscales with AI. In games with good DLSS implementation:

• DLSS Quality often looks better than native TAA at the same resolution
• FPS gains of 20–40% are common
• Use Quality mode for visual parity, Balanced or Performance when you need more FPS

DLSS 3 Frame Generation (RTX 40-series only) generates intermediate frames for 1.5–2x frame rate multiplier. Adds ~20ms latency compared to rendered frames, but NVIDIA Reflex compensates.

In-Game vs Driver Settings

The rule: in-game settings take precedence over driver settings for the same feature. Set V-Sync, anti-aliasing, and sharpening in-game when possible. Use driver settings as global defaults for apps that don't expose the option.

One thing worth saying: these settings won't add 50 FPS by themselves. What they do is remove self-imposed limits — keeping your GPU at full clock speed, cutting the render queue, and stopping Windows from interfering with power management. On top of a clean driver install, the combined effect is meaningful. For the OS-level changes that work alongside these driver tweaks, see best Windows settings for gaming in 2026.
