How To Optimize Gaming Pc For Ray Tracing

by

If you want to enjoy the stunning lighting and reflections in the latest games, you need to know how to optimize gaming pc for ray tracing. This guide gives you clear, step-by-step instructions to get the best performance without sacrificing too much visual quality.

Ray tracing makes games look incredibly realistic. It simulates how light actually behaves. But this comes at a huge cost to your PC’s performance. A poorly optimized system will struggle with low frame rates. Let’s fix that.

How to Optimize Gaming PC for Ray Tracing

This main section covers the core principles. Optimization is a mix of hardware checks, software settings, and in-game adjustments. We’ll start with the most important foundation: your hardware.

1. Start With a Hardware Reality Check

You can’t optimize what isn’t there. Ray tracing is extremely demanding. Before tweaking settings, ensure your PC meets the basic requirements.

  • GPU (Graphics Card): This is the most critical part. You need an NVIDIA RTX or AMD RX 6000 series or newer. Older cards might support it, but performance will be poor.
  • CPU (Processor): A modern CPU is essential. It handles game logic and feeds data to the GPU. An older CPU will bottleneck a powerful graphics card.
  • RAM (Memory): 16GB is the absolute minimum for modern ray-traced games. 32GB is becoming the recommended standard for a smooth experience.
  • Storage: Install games on a Solid State Drive (SSD). It drastically reduces loading times and texture pop-in, which is more noticeable in detailed ray-traced worlds.

2. Update Your Critical Drivers

Outdated drivers are a common cause of poor performance and crashes. This is a simple fix with big impact.

  1. For NVIDIA users: Use GeForce Experience or visit NVIDIA’s website to download the latest Game Ready Driver.
  2. For AMD users: Use the Radeon Adrenalin software or AMD’s website for the latest driver.
  3. Don’t forget chipset drivers for your motherboard. These can improve system stability and are often overlooked.

3. Master In-Game Graphics Settings

This is where you’ll spend most of your time. Every game is different, but these settings universally affect ray tracing performance.

Ray Tracing Presets & Core Settings

Most games offer presets like “Ray Tracing: Low, Medium, High, Ultra.” Start with Medium. The visual difference between High and Ultra is often small, but the performance hit is huge.

  • Ray Traced Reflections: The most common and impactful effect. Try lowering their quality or resolution first if you need frames.
  • Ray Traced Shadows: Can often be set to a lower quality without a massive visual drop.
  • Ray Traced Global Illumination (RTGI): This is the most demanding effect. It affects how light bounces in a scene. Use it sparingly unless you have a top-tier GPU.
  • Ray Traced Ambient Occlusion: Improves shadowing in corners. It’s less demanding than RTGI but still has a cost.

Essential Non-Ray Tracing Settings to Adjust

To make room for ray tracing, you often need to lower other settings. These offer good performance gains with minimal visual loss.

  1. Shadow Quality (Non-RT): Lower this to Medium. Since you’re using ray traced shadows, the base shadow quality matters less.
  2. Reflections (Non-RT): Same as above. If using RT reflections, set standard reflections to Low or Off.
  3. Ambient Occlusion (Non-RT): Turn this off if you’re using the ray traced version.
  4. Volumetric Fog/Lights: These are very demanding. Setting them to Medium can free up significant resources.
  5. Screen Space Reflections (SSR): Usually turned off automatically when RT reflections are on, but double-check.

4. Enable Upscaling Technologies (DLSS, FSR, XeSS)

This is the single most important performance trick for ray tracing. Upscaling renders the game at a lower resolution and uses AI or algorithms to upscale it to your monitor’s resolution. It looks great and boosts FPS massively.

  • NVIDIA DLSS (Super Resolution): Available on RTX cards. Set it to “Quality” or “Balanced” mode for the best mix of image quality and performance.
  • AMD FidelityFX Super Resolution (FSR): Works on most GPUs, including NVIDIA. FSR 2 or 3 is recommended. Use “Quality” mode.
  • Intel XeSS: Works on many GPUs, often with an AI boost on Intel Arc cards.

Always enable one of these. The performance gain is essential for smooth ray tracing.

5. Tweak Your GPU Control Panel Settings

Both NVIDIA and AMD have control panels that let you set global or per-game 3D settings. Here are key ones for ray tracing:

NVIDIA Control Panel (for RTX Users)

  1. Open NVIDIA Control Panel > Manage 3D Settings.
  2. Under “Global Settings” or “Program Settings” (for a specific game):
  3. Set Power Management Mode to “Prefer Maximum Performance.”
  4. Ensure Texture Filtering – Quality is on “High Performance.”
  5. Low Latency Mode can be set to “Ultra” if you have a powerful GPU, otherwise “On.”

AMD Adrenalin Software (for RX Users)

  1. Open AMD Adrenalin Software > Performance > Tuning.
  2. Ensure GPU tuning is enabled for a custom profile.
  3. Consider enabling Radeon Anti-Lag for better responsiveness.
  4. Check that Radeon Image Sharpening is on to help clarity when using upscaling.

6. Optimize Your Windows OS

Background tasks can steal precious resources from your game. A clean Windows setup helps.

  • Game Mode: Make sure Windows Game Mode is ON (Settings > Gaming > Game Mode). It helps prioritize your game.
  • Background Apps: Disable unnecessary apps running in the background (Settings > Privacy > Background apps).
  • Startup Programs: Stop programs from launching at startup (Task Manager > Startup tab).
  • High Performance Power Plan: Select the “High Performance” power plan (Control Panel > Hardware and Sound > Power Options).

7. Monitor and Manage Thermals

Ray tracing pushes your GPU and CPU hard, generating more heat. If your components overheat, they will throttle their speed to cool down, causing stutters and low FPS.

  1. Use software like MSI Afterburner or HWMonitor to check your GPU and CPU temperatures while gaming.
  2. Aim for below 85°C for your GPU and below 80°C for your CPU under load.
  3. Ensure your PC case has good airflow. Clean dust from filters, fans, and heatsinks regularly.
  4. Consider improving your fan curves (using software like Afterburner) to be more aggressive at lower temperatures.

8. Advanced Tweaks for Enthusiasts

If you’ve done all the above and want to squeeze out more frames, these steps are more involved.

Overclocking Your GPU (Safely)

A mild overclock can give you a free performance boost. Use MSI Afterburner.

  1. Increase the Core Clock slider by +50MHz. Test in a game for stability.
  2. Increase the Memory Clock slider by +100MHz. Test again.
  3. Increase in small increments and test each time. If the game crashes, lower the clocks slightly.
  4. Monitor temperatures closely during this process.

Undervolting Your GPU

This can reduce heat and power draw while maintaining the same performance, preventing thermal throttling. It’s often safer than overclocking. Search for a guide specific to your GPU model.

9. Per-Game Optimization Examples

Let’s look at two popular ray-traced games as practical examples.

Example 1: Cyberpunk 2077

  • Start with the “Ray Tracing: Medium” preset.
  • Enable DLSS Super Resolution or FSR in “Quality” mode.
  • Turn Ray Traced Reflections to Medium if needed.
  • Consider turning Ray Traced Lighting to Medium or even off—it’s very demanding.
  • Lower “Cascaded Shadows Range” and “Volumetric Cloud Quality” to Medium.

Example 2: Alan Wake 2

  • This game is build around ray tracing. Use the “Medium” or “Low” RT preset.
  • DLSS/FSR is mandatory for good performance. Use “Performance” or “Balanced” mode if needed.
  • Reduce “Mesh Quality” and “Texture Resolution” one step if you’re low on VRAM.
  • Post-processing effects like Motion Blur can be lowered or turned off.

  10. Test & Iterate: Play for 15 minutes. If performance is good, stop. If not, lower one more setting and repeat.

Frequently Asked Questions (FAQ)

Is ray tracing worth the performance hit?

That depends on you. If you value visual immersion and have hardware that can handle it at a smooth frame rate (like 60 FPS), then yes. If you’re a competitive gamer who needs max FPS, it’s often not worth it.

Can I use ray tracing without an RTX card?

Yes, but with limitations. AMD RX 6000/7000 cards support it. Some older GPUs can run it via software, but the performance is usually too slow to be enjoyable. A dedicated RT core (on NVIDIA RTX or AMD RX 7000+) is highly recommended.

Why is my FPS so low with ray tracing on?

The most common reasons are: your GPU isn’t powerful enough, you haven’t enabled DLSS/FSR, other in-game settings are too high, your drivers are outdated, or your CPU is bottlenecking the system. Follow the checklist above to find the issue.

Does ray tracing use more VRAM?

Yes, significantly. Ray tracing requires storing and processing more lighting data. If you’re running out of VRAM, lower texture quality and some of the RT settings, as they are the biggest VRAM users.

Should I turn off ray traced shadows?

Ray traced shadows are often one of the less noticeable effects compared to reflections and global illumination. If you need performance, turning them off or to a low setting is a good first step.

What’s the difference between DLSS and FSR?

DLSS is NVIDIA’s AI-based upscaler, requiring RTX hardware. FSR is AMD’s open-source spatial upscaler that works on many GPUs. Both aim to do the same thing: boost FPS. DLSS often has a slight edge in image quality, but FSR is a great option for non-RTX users.

Final Thoughts

Learning how to optimize gaming pc for ray tracing is an ongoing process. New games and technologies arrive constantly. The key is to start with a solid hardware foundation, always use upscaling, and adjust settings one by one. Don’t chase the “Ultra” preset. A smooth, stable frame rate with a mix of High and Medium ray tracing settings will always look and feel better than a stuttering slideshow on Ultra. Remember to keep your system clean and updated, and most importantly, have fun with your beautifully lit games.
