Unreal Engine 5 Games: Achieving Optimal Performance with Resolution Scaling

A co-founder of Infuse Studio, Jacob Sutton, has shed light on a critical aspect of Unreal Engine 5 (UE5) games. Contrary to expectations, running games natively at 4K in the engine alone does not guarantee a desirable frame rate. According to Sutton, Unreal Engine 5 enforces the use of Temporal Super Resolution (TSR) due to this limitation.

During an interview with Moore’s Law Is Dead, Sutton discussed various issues faced by Unreal Engine, including shader compilation on PCs. Surprisingly, the focus shifted to resolution, and it was revealed that UE5 struggles to run games smoothly at native 4K resolution.

Sutton specifically highlighted this concern while discussing software-based AMD FidelityFX Super Resolution (FSR) and hardware-based Nvidia Deep Learning Super Sampling (DLSS). He remarked that it’s unlikely to find any game on UE5 offering a satisfying experience at native 4K without employing upscaling techniques to achieve a desirable frame rate.

Host Tom clarified that this decision is primarily driven by the game engine itself, as opposed to developers specifically requesting it. Sutton agreed with this viewpoint, cementing the fact that Unreal Engine 5 mandates the use of upscaling techniques for optimal performance.

Although Unreal Engine 5 is still relatively new, these revelations raise questions about its true power. While Sutton’s experiences shape his standpoint, it remains unclear what frame rate is deemed acceptable and how it fluctuates based on personal preference. Unfortunately, the discussion does not provide any clarification on this matter.

The conversation quickly transitions to the rumored super resolution technology for PlayStation, leaving the issue of native 4K performance in Unreal Engine 5 unaddressed.

The positive takeaway from this discussion is that employing techniques like Nvidia DLSS, AMD FSR, Intel XeSS, or TSR can ensure excellent performance, even if it’s not at native 4K. However, it’s worth noting that achieving such results would require high-end hardware, such as the Nvidia GeForce RTX 4090.

– Intel’s XeSS is another upscaling technique that can be used to improve performance in games.
– High-end hardware, such as the Nvidia GeForce RTX 4090, is recommended to achieve excellent performance with these upscaling techniques.

Important Questions:
1. Does Unreal Engine 5 require upscaling techniques to achieve optimal performance?
2. What are some popular upscaling techniques mentioned in the article?
3. How does high-end hardware, like the Nvidia GeForce RTX 4090, affect performance when using upscaling techniques?

Key Challenges or Controversies:
– One key challenge is determining the acceptable frame rate for a satisfying gaming experience at 4K resolution.
– There might be controversy around the reliance on upscaling techniques rather than native 4K resolution in UE5 games.
– The effectiveness and quality of different upscaling techniques, such as DLSS, FSR, and XeSS, might be a topic of debate among gamers and developers.

Advantages:
– Using upscaling techniques can improve performance in Unreal Engine 5 games, even if they are not running at native 4K resolution.
– Higher frame rates can lead to smoother gameplay and a more immersive gaming experience.
– The availability of multiple upscaling techniques provides options for developers to optimize their games for different hardware configurations.

Disadvantages:
– Upscaling techniques may introduce artifacts or reduce image quality compared to native 4K resolution.
– High-end hardware requirements for optimal performance with upscaling techniques may limit access for some gamers.
– The reliance on upscaling techniques instead of native 4K resolution might be seen as a compromise in visual fidelity.
