Introduction

Hey everyone! In this article, I'll be taking a deep dive into some of the settings in the latest version, 2.9, of DCS (Digital Combat Simulator). I'll be discussing the pros and cons of each setting, as well as any conflicts or issues they may have. If you're experiencing any difficulties or have noticed certain behaviors, don't worry, you're not alone. I'll shed some light on these matters and provide insight into how to optimize your experience. So, let's get started!

DLSS: The Good and the Bad

🚀 Improvement with DLSS

One of the standout features in DCS 2.9 is DLSS (Deep Learning Super Sampling), which promises a significant improvement in frame rates. If you can tolerate some ghosting, DLSS can provide you with smooth gameplay and excellent performance.

⚡️ Ghosting Issues with DLSS

However, the downside of DLSS is the ghosting effect it introduces. This is particularly noticeable in fast-moving scenarios, such as dogfights, and can be amplified in VR. If you're someone who values image Clarity, especially during landings or when looking at distant objects, the ghosting might be a deal-breaker.

🤷‍♂️ DLSS and Different Hardware

While DLSS 2.5 may have its limitations, it's worth noting that performance and image quality may vary depending on your hardware. If you have a 40 series GPU, let me know in the comments if you're experiencing similar ghosting issues or if you're having a better visual experience.

FSR and NIS: Not Worth the Hype

❌ Underwhelming Results with FSR and NIS

Another set of settings introduced in DCS 2.9 is FSR (FidelityFX Super Resolution) and NIS (NVIDIA Image Scaling). However, after extensive testing, I found that the results did not live up to expectations. Many users have reported similar experiences, indicating that these settings offer minimal improvements compared to the Open XR toolkit. Therefore, I recommend skipping these settings for now.

SSS and Screen Space Shadows

🌑 Understanding Screen Space Shadows

Screen Space Shadows (SSS) is an essential setting for rendering accurate shadows based on the position of the sun and other light sources. It delivers impressive visual effects for objects in close proximity. However, at greater distances, SSS may exhibit some issues.

👀 Inconsistencies with DCS Screen Space Shadows

In DCS 2.9, some users have reported problems with SSS, particularly when it comes to rendering shadows on grass and objects at a distance. While the grass and terrain Shadows look great up close, there is a jarring transition as you move further away. Additionally, artifacts may be observed at the edges of the screen due to the limitations of screen space effects.

The Issue with DLSS and Screen Space Shadows

⚠️ Compatibility Problems

One notable issue arises when using DLSS and screen space Shadows simultaneously. At certain angles, the Shadows become distorted and can even darken the entire terrain. This problem seems to be specific to DLSS and screen space Shadows working together. If you encounter this issue, try disabling one of these settings until a fix is provided by the developers.

Alleviating the Artifacts with Flat Shadows

🌳 Making Shadows Look Better

To address the limitations of screen space Shadows, there is an alternative option available: Flat Shadows. While choosing Flat Shadows may result in a slight performance hit, it supplements the screen space Shadows where they fall short. This combination creates a more visually pleasing experience, especially when it comes to rendering shadows on the ground.

LOD Switch Factor: Changing Level of Detail

🔁 Modulating Level of Detail

The LOD (Level of Detail) Switch Factor setting allows you to adjust the distance at which different levels of detail are rendered. By setting a higher value, objects in the distance will retain more details, while a lower value reduces the level of detail at greater distances. This setting can improve performance, particularly for machines struggling with high levels of detail.

Sharpening: A Cool Feature

🔪 Enhancing Image Clarity

DCS 2.9 introduces a sharpening feature, which is a welcome addition for many players. Previously, users had to rely on external tools like Reshade to achieve a similar effect. This built-in feature provides a crisper image, enhancing visual fidelity. While the sharpening effect may not be as noticeable in VR, it still contributes to a cleaner and more defined picture, especially when recording gameplay.

Recording VR in DCS

📹 Capturing Your VR Adventures

If you enjoy recording your VR experiences in DCS, I've got good news for you. With the latest update, there are built-in options for capturing gameplay footage. Stay tuned for an upcoming video where I'll dive deeper into the process and share tips to help you create stunning VR recordings.

Conclusion

That wraps up our exploration of the key settings in DCS 2.9. We've discussed the pros and cons of DLSS, FSR, NIS, SSS, and the LOD Switch Factor. We've also touched on the challenges posed by DLSS and screen space Shadows, as well as the workaround with Flat Shadows. Additionally, we've highlighted the benefits of the new sharpening feature and the convenience of in-Game recording for VR. Experiment with these settings to find the optimal balance between performance and visual quality. Happy flying!

FAQ

Q: Can I use DLSS and screen space Shadows together?
A: While it is possible, some users have reported compatibility issues with distorted Shadows and darkening of terrain. It is recommended to disable one of these settings if you encounter such problems.

Q: Are FSR and NIS worth enabling?
A: Based on user feedback and extensive testing, the improvements offered by FSR and NIS are minimal compared to the Open XR toolkit. It is advisable to skip these settings for now.

Q: How can I improve shadow rendering in DCS?
A: Combining screen space Shadows with Flat Shadows provides a better Shadow rendering experience, especially for objects at a distance. Adjusting the LOD Switch Factor can also enhance performance and visual quality.

Q: Does DLSS work better with a 40 series GPU?
A: While DLSS performance may vary depending on your hardware, it is difficult to determine whether 40 series GPUs offer better results without user feedback. If you're using a 40 series GPU, please share your experiences in the comments.

Q: Is the sharpening feature beneficial in VR?
