To put it mildly, Leslie Benzies is embarrassing himself, and it’s probably going to embarrass publisher IO Interactive, too.

Build a Rocket Boy‘s game released this week, and it looks like another Unreal Engine 5 title that can only achieve 4K/60 FPS with Nvidia‘s DLSS and frame generation technology, even on one of the most powerful video cards available. A video by MxBenchmarkPC shows how the game runs on an RTX 5080 at both 4K and 1440p resolutions.

Both resolutions should be easily handled by the video card. Unfortunately, the game is yet another title that brings the GPU to its knees thanks to Unreal Engine 5. At 4K, MindsEye only achieves an acceptable frame rate using Nvidia DLSS Quality mode and frame generation, and only Multi Frame Generation delivers a high-refresh-rate experience at this resolution. At 1440p, the situation is only marginally better, but the fact that the game runs at around 60 FPS at native resolution suggests that no GPU besides the RTX 5090 can properly handle it in its current state.

Players can’t take the game seriously, either. Currently, there are 1,237 reviews on Steam, and only 40% are positive. This barely puts it in the “mixed” category on Valve’s digital platform. Most criticism focuses on performance, stability, and AI issues. Players have shared numerous bugs and malfunctions online. Two executives left Build a Rocket Boy before launch, and the game’s subreddit posted a statement:

“Thank you to all who joined us as pioneers on day one. We understand that the current minimum specifications are very high, but our engineering team is working around the clock to improve performance on mainstream hardware, as well as on consoles, by integrating performance improvements in Unreal Engine 5.6. We will provide the timing for patch 3, which includes these improvements, within the next 24 hours,” the studio wrote.

One respondent said the game should have been delayed 2-3 months because the scenes, city, and story are fine, but gameplay lacks spark, console performance is chaotic, and NPC movement is a glitchfest. Another found it unacceptable that MindsEye runs at 25 FPS on PlayStation 5 Pro. The Twitter videos below show some of the glitches.

This was/is tomorrow’s intro for our early review, but I’ve not seen anyone posting glitches like this yet.
