Spreading democracy across the galaxy in Helldivers 2 is difficult but glorious work, so it's important to arm yourself with the most effective equipment possible. This is true for both your in-game loadout and the components in your PC, and it turns out that an Nvidia graphics card will help your missions run more smoothly than an AMD GPU.
While it's well understood that Helldivers 2 as the game doesn't feature any RT effects but, strangely, this doesn't appear to be the case.
Comparing Helldivers 2 frame rates captured on the Radeon RX 7900 XT, the performance gap is surprisingly large. At best, team red's pixel pusher falls behind by 31fps at 4K but its worst result sees a 56fps delta at 1080p.
This is according to findings by Core i9 14900K, so there's limited danger of processor bottlenecks here.
It's worth noting that the outlet did capture its Helldivers 2 performance data in the game's ship instead of being knee-deep in bugs or bots. This does help maintain parity between tests as this environment is much less dynamic than missions, but they're not wholly indicative of performance planet-side. Even so, there's little reason to believe the frame rate gap observed here would disappear in a place in desperate need of democracy.
There doesn't appear to be a clear explanation for why the RX 7900 XT lags behind the RTX 4080 by such a margin, especially given Helldivers 2 would have been primarily developed for the PlayStation 5 (which uses an AMD RDNA 2 GPU). Whether there's optimizations to be made with the game itself or in team red's drivers is anyone's guess, but we can only hope the performance gap closes with subsequent updates.
