Best PUBG settings for RTX 3090 Ti
Recommended at 4k: expect 134–171 FPS after applying the playbook below. Range derived from published benchmark measurements for this game. RTX 3090 Ti pairs cleanly with PUBG — no single component is the wall.
Your RTX 3090 Ti and PUBG are paired well — neither is the runaway bottleneck. The biggest FPS gains come from a balanced cut: drop a couple of expensive effects (shadows, volumetrics) without touching what makes the game look like PUBG.
Apply these settings in PUBG
Ranked by FPS impact for tier S hardware. Apply the high-impact ones first — top three usually account for 60% of the gain.
NVIDIA-specific tweaks
These are in NVIDIA Control Panel + GeForce App.
Single biggest input-latency improvement on NVIDIA. ~10–25 ms reduction depending on title. Always on.
Windows Settings → Display → Graphics. Enables CPU offload for GPU work scheduling. Small but consistent gain.
NVIDIA Control Panel → 3D Settings → set per game. Forces full clocks during play.
How PUBG runs on RTX 3090 Ti
PUBG runs on the Unreal Engine 4 engine. At 24GB VRAM, the RTX 3090 Ti handles this engine's rendering pipeline with some settings adjustments. The engine's competitive multiplayer renderer prioritizes consistent frame times over visual fidelity, making settings optimization meaningful for S-tier hardware.
At this hardware tier, every setting matters. Start with everything on Low, then selectively raise Texture Quality and Anti-Aliasing if you have FPS headroom above your target.
Known quirks for RTX 3090 Ti in PUBG
- •Monitor VRAM usage in-game — 24GB can be tight at Ultra settings
- •Enable NVIDIA Reflex if available for lower input latency
- •Update NVIDIA drivers before optimizing — stale drivers can leave 5-10% FPS on the table
How we rank these settings
BetterFPS ranks each setting by its FPS-per-quality-cost ratio for your GPU tier. We pull from engine documentation, community benchmarks, and driver release notes to estimate each setting's render cost on NVIDIA S-tier hardware at 4k. High-impact settings are those where disabling or lowering them recovers significant frame time with minimal perceptible quality loss. The personalized optimizer refines these further using your CPU, RAM, and monitor refresh rate.
About the RTX 3090 Ti
The RTX 3090 Ti (2022 release, 24GB VRAM) is a flagship card. At 4k in PUBG, the biggest FPS levers are upscaling, shadow detail, and brand-specific latency reducers (NVIDIA Reflex). The settings above are the floor — for a fully personalized playbook factoring CPU, RAM, and your monitor refresh rate, run BetterFPS.
