I went into the Arknights: Endfield tech test expecting "Auto" to be fine, then watched my frame time graph turn into a heartbeat monitor. If you want a quick shortcut before you start experimenting, Arknights endfield boosting is one of those phrases you'll see tossed around by players chasing smoother runs and faster progress. Still, the real win is learning which settings actually hit performance, because UE5 will happily burn through headroom you didn't know you had.

Start With the Heavy Hitters

You'll notice it fast: shadows, volumetric fog, and reflections are the usual suspects. Drop shadows first, then fog, then reflections, and test after each change. Don't do it all at once or you won't know what helped. I'd also keep effects and post-processing a step lower than textures—textures rarely tank FPS the way lighting does. If the game's got a "global illumination" or "distance field" style option tucked in there, trimming it can calm down those random spikes when the camera swings.

Frame Rate and Upscaling Choices

People love chasing 120, but a steady 60 often feels better than a shaky 90 that jitters every fight. Cap it and let your GPU breathe; the game stops lurching when explosions hit or when you spin the camera in a busy hub. If you're on Nvidia, DLSS Balanced is the comfy middle ground—sharp enough in motion, big enough boost to keep frametimes tidy. If you're not on DLSS, use whatever upscaler the build offers, but avoid stacking it with aggressive sharpening because it can make foliage shimmer like crazy.

Driver and Windows Tweaks That Actually Matter

This part's boring, but it's where a lot of "why does it feel weird?" complaints come from. Set your GPU power plan to Prefer Maximum Performance so it doesn't downclock mid-fight. Nvidia Reflex on can make aim and camera feel snappier, and yeah, I've had better luck with Windows Game Mode off in some UE5 titles. Also, skip the one-click "optimize" tools. They'll change internal resolution, flip odd defaults, and you end up troubleshooting a mess you didn't choose.

DX11 vs DX12, Storage, and Those Random Hitches

If stutters won't quit, swap APIs. Start with DirectX 11, then try DirectX 12, because some rigs behave the opposite of what you'd expect. Make sure it's on an SSD; streaming off an HDD is basically asking for micro-stutter. And if performance degrades after a long session, just restart—there's a whiff of memory leak in these test builds. If you're the type who wants the smoother ride without spending your whole night tweaking, it's no surprise folks look up Arknights endfield boosting buy while they wait for the next patch to tighten things up.
