Unreal Engine 5: The Performance Conundrum
Unreal Engine 5 is becoming the game engine of choice for many studios, offering a host of benefits and new capabilities. However, it also has its downsides, particularly when it comes to performance.
The Performance Issue
While the big consoles can cope with Unreal Engine 5 games, it’s a different story for PCs. Even the best laptops for game development can struggle with resource-hungry Nanite and Lumen, and PC gamers still often complain of hazier, unstable visuals.
A Developer’s Perspective
Bryan Heemskerk, a developer from Massive Damage, discussed the issue on the Broke Silicon podcast. He suggested that at launch, Unreal Engine 5 was "two GPU generations off being performant". He pointed out that consoles have dedicated IO controllers to handle data compression and decompression, whereas PCs face data bottlenecks that prevent smooth performance.
Waiting for the Next Generation
Bryan suggests that we might need to wait for the next generation of components before they catch up. He mentioned that the Nvidia GeForce RTX 6000 series "will probably run Unreal Engine 5 really well". This implies that we have something to look forward to perhaps in 2026 or 2027, when latency and interface speed will be low enough to support the engine’s demands.
Alternative Options
Unreal Engine 5 is meeting the demands of game developers, who want capabilities for more complex technical art and more believable character movement. However, Bryan suggests that there’s an argument for using older versions of the engine if you’re not going to use the full feature set of the latest version.
Conclusion
Unreal Engine 5 is pushing the boundaries of game development, offering new possibilities for game developers. However, its demanding requirements may outstrip the capabilities of current hardware, particularly for PCs. As the technology continues to evolve, we can expect to see improvements in performance, but for now, developers may need to weigh the benefits against the costs.
