What These RTX 5090 Benchmarks Really Prove
RTX 5090 benchmarks in Beast of Reincarnation show that a modern flagship GPU can sustain 90–110 FPS at native 4K with max settings, giving a realistic view of high-end 4K gaming performance in a current Unreal Engine 5 action RPG rather than a synthetic test or tech demo.
The headline result is blunt: at Native 4K/Max Settings, Beast of Reincarnation runs with 90-110FPS on an NVIDIA GeForce RTX 5090. For a game powered by Unreal Engine 5.4.4.0 with Ray Tracing support, that is more than a bragging-rights number; it is a statement about where real-world 4K gaming performance lands today. One quotable takeaway is that "for gaming at Native 4K/Max Settings with 60FPS, you will need an NVIDIA RTX 5090 or an RTX 4090," which draws a clear line between flagship GPUs and the rest of the stack. This is not about theoretical ceilings; it is about an action RPG, built by the developers of the latest Pokémon games, behaving like a true high-refresh 4K title under maximum load.
The Test Bed: Flagship GPU Testing in a Real UE5 Game
These RTX 5090 benchmarks are grounded in a consistent high-end platform rather than cherry-picked scenes or marketing slides. Both the early impressions and the broader PC performance analysis used an AMD Ryzen 9 7950X3D paired with 32GB of DDR5 at 6000Mhz, and an NVIDIA GeForce RTX 5090 for initial 4K gaming performance testing. That matters because Beast of Reincarnation mostly uses six CPU cores/threads and can be CPU bottlenecked at 1080p, especially on weaker processors.
On the GPU side, the flagship GPU testing did not stop at the RTX 5090. The benchmark suite included AMD’s Radeon RX 6900XT, RX 7900XTX, RX 9070XT, along with NVIDIA’s RTX 2080Ti, RTX 3080, RTX 4090 and RTX 5080, all driven on Windows 10 64-bit with current drivers. According to the analysis, "at 1440p/Max Settings, our top five GPUs had no trouble running the game with over 60FPS at all times," which paints Beast of Reincarnation as more demanding at 4K than at lower resolutions. Put simply, the 5090’s 4K lead is not because the game is easy; it is because this card is a different class.
4K Gaming Performance: Where the RTX 5090 Pulls Ahead
If you care about 4K gaming performance, Beast of Reincarnation is a useful stress test. At 1080p/Max Settings, even an RTX 2080Ti can hit an average of 73FPS, and all tested GPUs manage 60FPS or more. By 1440p, the top five cards stay comfortably above 60FPS, while mid-high options like the RTX 3080 and RX 6900XT remain playable with adaptive sync displays. The real separation happens at native 4K.
At Native 4K/Max Settings, the data is crystal clear: the RTX 5090 delivers 90–110 FPS in the game’s tutorial area and similar loads, with everything maxed. The wider analysis confirms that for gaming at Native 4K/Max Settings with 60FPS, you will need an NVIDIA RTX 5090 or an RTX 4090, while the RTX 5080 can hold a smooth experience if you use a G-Sync monitor. For players aiming at 4K high-refresh displays, this makes the RTX 5090 one of the few cards that can stay well above the 60FPS floor instead of hovering around it. That is the practical definition of flagship 4K gaming performance today.
Unreal Engine 5 Gaming Without the Heavy Visuals
On paper, Beast of Reincarnation is a cutting-edge Unreal Engine 5 game using version 5.4.4.0 and supporting Ray Tracing. In practice, its visuals are more conservative, and that shapes how we should read these RTX 5090 benchmarks. The game appears not to use Lumen or Nanite, with many areas looking flat and lighting that fails to match more advanced UE5 titles. Graphics-wise, it even "looks like an old-gen title" with a lot of pop-ins, old-feeling lighting, and numerous low-res textures called "PS3 textures" on max settings.
Ray Tracing is another point of frustration. The setting supposedly upgrades lights and shadows, but testing shows no clear visual difference between RT On and RT Off, and performance remains the same, suggesting the feature may be broken. Meanwhile, traversal stutters remain present, though minimized on the 7950X3D; users with less powerful CPUs have reported trouble, underlining that a modern-day CPU is important to keep high framerates and reduce hitches. In other words, this is Unreal Engine 5 gaming stripped of its heaviest tech, which helps performance but keeps the RTX 5090 from being pushed by the most advanced visual features the engine can offer.
Who This Benchmark Matters For—and What It Does Not Say
These RTX 5090 benchmarks matter most for high-end PC gaming fans, the kind of players who follow PC performance analysis writers that support modding and indie communities and who care about flagship GPU testing beyond raw marketing. If you are planning a new build around 4K gaming performance and Unreal Engine 5 gaming, Beast of Reincarnation offers a useful data point: the RTX 5090 can comfortably drive native 4K max settings at 90–110 FPS in a current action RPG with real gameplay, not a synthetic scene.
However, this benchmark is not a complete verdict on future UE5 blockbusters. The game’s graphics shortcomings—old-gen lighting, heavy pop-in, and low-res textures—mean it does not pressure the RTX 5090 with full-fat Lumen or Nanite effects. It shows that a modern-day CPU and a wide range of GPUs can run it smoothly, but weaker processors may struggle and traversal stutters can still appear. The fair conclusion is this: Beast of Reincarnation proves that the RTX 5090 is more than ready for today’s lighter UE5 workloads at 4K, yet we still need more visually ambitious titles to judge how far this flagship can go when every cutting-edge feature is turned on.
