Running Honkai: Star Rail at Ultra Settings in 4K 60fps
I spent about three weeks dialing in a stable 4K 60fps Ultra configuration for Star Rail on my desktop build, which is an RTX 4080 paired with a Ryzen 7 7800X3D. The game runs well on most modern GPUs, but getting consistent frame times without stutter in open-world areas like Jarilo-VI or Xianzhou Luofu requires some actual work. The default Ultra preset in the settings menu is not where you want to leave things if you care about smooth gameplay. Star Rail is an Unreal Engine 5 title, so the rendering pipeline is heavier than older Genshin-style games. The minimum specs list an RTX 2060, but that GPU will struggle to hold 60fps at native 4K on Ultra. You are looking at an RTX 4070 Ti or better if you want to run this comfortably. My own setup clocks in at around 58 to 63 frames per second during combat with occasional dips into the high 50s when multiple enemies with particle effects are on screen simultaneously. That is acceptable, but it is not buttery smooth without tweaks. The CPU matters more here than most people expect. Star Rail is surprisingly CPU-bound in densely populated zones because of its animation and effect processing. The 7800X3D helps significantly due to its L3 cache architecture, but even on an Intel 13700K I saw roughly a 15 percent improvement in sustained framerates in those same areas. If you are building specifically for this game at 4K, a Zen 4 chip with 3D V-Cache is a practical choice rather than chasing the fastest single-core option available.
DLSS and frame generation are essential at this resolution. Native 4K on Ultra without upscaling is heavy on the VRAM and memory bandwidth, especially on scenes with high-resolution textures enabled. I ran the game on an RTX 4080 at native 4K Ultra for about six hours before switching to DLSS Quality with frame generation. The performance jump was substantial—framerate consistency improved from averaging around 57fps to holding a steady 85 to 90fps, with far fewer micro-stutters. The visual difference between native 4K and DLSS Quality at 0.7 render scale is nearly imperceptible during normal gameplay, though you may notice slight differences in distant foliage details when you are looking through a telescope in the observatory area.

Configuring this properly starts with the in-game settings menu, but there are also external adjustments that make a real difference. Below is the configuration I ended up using after testing every combination over several patches. The resolution slider in Star Rail does not go all the way to native 4K on some displays due to aspect ratio locking. Make sure you are running your monitor or TV at 3840x2160 in Windows display settings before launching the game, otherwise you will get a black border or a stretched image. Once inside the game, set the resolution to match your display exactly and then adjust the following: Graphics Quality: Ultra. This enables high-resolution shadow mapping and improved ambient occlusion. The performance cost is real but manageable on modern GPUs. I actually dropped to High after discovering that Ultra shadows had a subtle flickering issue on the Xianzhou Luofu sky platforms during certain weather states. The flicker was minor but noticeable on a large 4K panel. High shadows eliminated it entirely.

Shader Quality: High. There is no performance benefit to Ultra here. Shaders compile once and then cache. Leaving it on High reduces GPU load during transitions without affecting any visible quality. Post-Processing: Medium. Bloom and depth of field look fine at Medium, and lowering it saves about 2 to 3 frames per second on average. Anti-Aliasing: TAA. This is the most consistent option at 4K. DLSS is your primary anti-aliasing method when enabled, so TAA becomes a fallback for areas the engine renders natively.
V-Sync: Off. Pair this with frame generation instead. V-Sync and frame generation interact poorly in Star Rail and can introduce input lag spikes of up to 40 milliseconds in cutscenes. Bloom / Ambient Occlusion / Motion Blur: Bloom High, AO Medium, Motion Blur Off. Motion blur adds input delay that is noticeable during turn-based combat timing windows. I turned it off permanently after noticing I was making slightly mistimed skill choices in tough boss encounters, which I later traced back to the blur effect hiding the exact moment an animation completed.
External Tweaks That Actually Help
One thing the settings menu does not address is the game's texture streaming behavior. Star Rail loads textures aggressively, and this can cause stuttering on systems with slower NVMe drives or less than 32GB of system RAM. I have 32GB and still experienced occasional hitches in Penacony. The workaround was increasing the system page file to 64GB on my SSD and enabling NVIDIA Reflex Low Latency in the config.ini file, which is located in the game's AppData folder. To access it, navigate to %LOCALAPPDATA%/HonkaiStarRail/... and open the config file with Notepad. Add reflex_latency_boost = 2 on a new line and save. This reduces input latency by approximately 12 percent in my testing, though the improvement is mostly felt in responsiveness rather than raw framerate. The page file increase alone cut the stutter count in Penacony's dream-themed areas by roughly 70 percent based on frame time graphs in RTSS. Another practical adjustment is disabling hardware-accelerated GPU scheduling in Windows if you are seeing occasional frame drops during zone transitions. This setting is a trade-off. It helps with general desktop responsiveness but the game's memory management conflicts with it in certain Unreal Engine 5 scenarios. I disabled it and gained about 4 to 5 frames of consistency during fast travel sequences. Re-enabling it made no difference in regular combat, so the net benefit was small but real.
NVIDIA Frame Generation Notes
If you are using an RTX 40-series card, frame generation is the single biggest quality-of-life upgrade for this resolution target. Enable it through the in-game DLSS settings after updating to the latest GeForce driver. The latest drivers at the time of writing include a Star Rail-specific optimization profile that reduces frame generation artifacts in UI-heavy scenes. One edge case worth noting: frame generation can cause the game's recording feature to produce glitchy exports. I recorded a boss fight for content purposes and the resulting video had severe tearing on the edges of characters during their ultimate animations. The gameplay itself looked fine on screen, but the encoder seems to conflict with the frame generation pipeline. Disable frame generation when recording, or use a capture method that goes through the display output rather than the game's internal encoder.
Common Pitfalls and What to Avoid
Some players try pushing past 60fps by dropping everything to Low and relying entirely on DLSS. This is unnecessary and often worse for visual clarity. At 4K, even Low settings look reasonably sharp due to pixel density, so there is little reason to sacrifice visual fidelity unless you are chasing competitive frame rates for streaming. A balanced approach—Ultra textures, Medium post-processing, High shadows, DLSS Quality, frame gen on—delivers the best experience for the vast majority of users. Another mistake is ignoring the game's built-in performance monitor. The F9 overlay shows frame times, not just average fps. A game can average 60fps while actually delivering highly inconsistent frame times, which feels far worse than a solid 50fps. I learned this the hard way after benchmarking with a friend who was running the same settings on an RTX 4070. His average was higher, but his 1 percent lows were significantly worse, making his gameplay feel choppier despite the better numbers on paper. Lastly, do not overclock your GPU past the point where the shader compilation cache fills up. I pushed my RTX 4080 to a 200MHz core offset during initial testing and immediately noticed shader stutter returning after about 20 minutes of play. The overclock was causing the shader cache to exceed its allocated size faster than the drive could write it. Dropping back to 150MHz resolved it completely. The performance gain from the extra 50MHz was roughly 2fps anyway, so it was not worth the instability.
