RTX 5090, performance in Subnautica 2? The reality of UE5 optimizationWe tested the latest RTX 5090 graphics card in Subnautica 2, built on Unreal Engine 5. At native 4K resolution, it struggled with 30-40 FPS, showing a lack of optimization. However, applying DLSS Quality settings significantly boosted performance to over 90 FPS. Adding frame generation technology further smoothed gameplay, but the optimization issues remain a disappointment.
1. 🎮 RTX 5090, Subnautica 2 4K Native Performance Test
· We tested the performance of Subnautica 2 using the latest RTX 5090 graphics card.
· At 4K resolution, epic graphics settings, and with DLAA applied, the average FPS recorded was 40, dropping to the 30s in some sections.
· This highlights the optimization issues in Unreal Engine 5-based games, failing to fully utilize the RTX 5090's power.
· The game is in early access, so there's potential for future optimization improvements.

2. 🚀 Performance Greatly Improved with DLSS Quality Settings
· Applying DLSS Quality settings at 4K resolution significantly increased the average FPS to over 90.
· This is more than double the performance compared to native resolution, making gameplay much smoother.
· The visual quality degradation with DLSS Quality settings is barely noticeable, providing satisfactory results.

3. ✨ Enhanced Experience with Frame Generation (FG) Technology Added
· We additionally applied Frame Generation (FG) technology on top of DLSS Quality settings.
· Frame Generation improves 1% low values and adds overall smoothness, enabling a more comfortable play experience.
· Latency is also kept low, with almost no input lag felt.
· However, as the game is in early access, Frame Generation options are limited, and some minor stuttering still exists.

4. 📈 DLSS Performance Settings and Frame Generation Disabled
· When switching to DLSS Performance settings and disabling Frame Generation, the average FPS remained around 100.
· Disabling Frame Generation showed a slight increase in latency, but the difference was not significant.
· This is analyzed as Frame Generation activating Reflex even without the in-game NVIDIA Reflex setting.

5. 🖥️ 1440p and 1080p Resolution Performance Tests
· At native 1440p resolution, average FPS exceeded 100, allowing for smooth gameplay.
· At 1080p resolution, FPS dropped to 60 in certain sections, indicating persistent optimization issues.
· Considering the RTX 5090's power, the current FPS at these graphics settings is somewhat disappointing.

6. 📊 4K Resolution Retest and VRAM Usage
· Retesting at 4K resolution with DLAA settings resulted in 40 FPS in specific sections.
· This performance was even lower than at 1080p, demonstrating severe issues with resolution scaling and optimization.
· VRAM usage was relatively low due to the texture quality not being excessively high.

7. 👍 Final Verdict: Playable, but Optimization is Lacking
· Despite being in early access, Subnautica 2 offers a playable level of performance by utilizing DLSS and Frame Generation technologies.
· However, the subpar performance in native settings even with a high-end GPU like the RTX 5090 clearly points to optimization deficiencies.
· There is room for optimization improvements through future updates.
