Best Settings for RTX 3090 Ti in Clair Obscur Expedition 33

Dial in these settings to get the most out of your RTX 3090 Ti in Clair Obscur Expedition 33 at 1440p and 4K.

The mighty 3090 Ti offers approximately a 12% performance improvement over the original RTX 3090 and about 20–25% over the RTX 3080 Ti when gaming at 4K, albeit with a much higher power draw. As of 2025, the 3090 Ti remains a powerful GPU for playing Expedition 33 at eye-candy settings. With some optimization, as mentioned below, the 3090 Ti can deliver a 60 FPS+ experience at native 1440p and upscaled 4K.

Note: The 3090 Ti can draw close to 500W at full load. If you’re overclocking, ensure your PSU is up to the task. That said, undervolting is a more reasonable approach—it reduces thermals and power draw while boosting GPU clocks, especially since Samsung’s 8nm node is more efficient at lower voltages. You may lose 1–2 FPS here and there, but you gain stability, a longer lifespan, lower power draw, and quieter operation.

A few keynotes to consider:

Since native Frame Generation is unsupported (both by the GPU and the game), you can mod it via Lossless Scaling or the OptiScaler mod. This helps reduce traversal stutter to an extent, an issue common in most UE5 games.
For the best image quality, use the Transformer mode; force-swap it via DLSS Swapper. This will help reduce the shimmering seen on Gustav’s curly hair in every cutscene, among many other problems.
Expect around a stable 60 FPS average across the entire game and multiple biomes. 1440p is suggested at Native AA; you can easily use Quality DLSS and then play for more FPS.

The 3090 Ti has sufficient raster performance and computing power to play UE5 Lumen-based (non-RT) games easily. You can use these settings as a baseline, customize them to your liking, and even use modded Framegen to improve them further.
