Best Baldur's Gate 3 Settings for FPS and Performance
Published
On this page
The fastest way to boost FPS in Baldur’s Gate 3 is to cap your frame rate to a rate the CPU can hold in Lower City, set the heavy sliders (Model Quality, Detail Distance, Cloud Quality) to Medium, and turn on DLSS or FSR Quality. Act 3’s Lower City is CPU-bound on crowd and NPC simulation, so graphics sliders barely move frames there — the real gains come from freeing CPU headroom and locking frame times. This guide covers the best graphics, CPU, and Windows settings for any PC.
The goal is steady frames while walking through a packed Lower City street — not maxed detail your CPU can’t feed no matter how strong your GPU is.
Why Baldur’s Gate 3 drops FPS in Act 3
Baldur’s Gate 3 runs beautifully in Acts 1 and 2, then frame rates fall in Act 3’s Lower City. The reason is the engine simulating a dense urban zone — dozens of NPCs, crowds, and systemic AI all running on the CPU. In that area frame times spike no matter how strong your graphics card is, because the GPU isn’t the bottleneck. Everywhere else the game is GPU-bound and runs far better. That split is the single most important thing to understand: in Lower City, lowering graphics settings barely helps — you have to cut CPU load and cap frames.
Best Baldur’s Gate 3 settings
Set these in Options → Video:
| Setting | Recommended value |
|---|---|
| Display Mode | Fullscreen |
| V-Sync | Off |
| Frame Rate Cap | Rate the CPU holds in Lower City |
| Upscaling (DLSS/FSR) | Quality |
| Model Quality | Medium |
| Detail Distance | Medium |
| Instance Distance | Medium |
| Texture Quality | Match VRAM (High 8GB+, Medium 6GB) |
| Shadow Quality | Medium |
| Cloud Quality | Low/Medium |
| Fog Quality | Medium |
| God Rays | Off |
| Ambient Occlusion (SSAO) | On (cheap) |
| Anti-aliasing | TAA / DLAA if you have headroom |
The heaviest GPU costs are Model Quality, Detail Distance, Cloud Quality, and God Rays. Dropping those to Medium/Off recovers real frames in the open acts. In Lower City, though, the frame cap and CPU headroom are what matter — not these sliders.
Frame pacing beats graphics in Lower City
Because the Act 3 drops are CPU-driven, a stable frame cap is the most effective single change:
- Use Fullscreen for the lowest input delay.
- Turn V-Sync off — cap your FPS instead.
- Cap to a rate the CPU sustains in Lower City (often
60 FPSon a strong CPU,45 FPSon an older one). - Keep the same cap everywhere so frame times stay flat between camp and city.
A locked, holdable cap turns a jarring 120-to-50 swing into an even experience. For the reasoning, see How to Cap Your FPS Correctly.
Free up CPU headroom
These matter more than any graphics setting in Act 3:
- Enable XMP/EXPO so your RAM runs at full rated speed — CPU-bound games benefit directly from faster memory. See How to Enable XMP or EXPO for Gaming.
- Install the game on an NVMe SSD so asset streaming in the city doesn’t add hitching.
- Disable VBS for extra CPU headroom in crowded areas.
- Close background apps (browsers, overlays, launchers) that steal CPU threads.
- On multiplayer/co-op, expect lower city frames — each connected player adds simulation load.
Upscaling for the open acts
Upscaling helps most where the game is GPU-bound — the wilderness of Acts 1 and 2 and higher resolutions.
- Set DLSS to Quality on RTX cards, or FSR to Quality otherwise, at 1440p and 4K for a solid boost with minimal clarity loss.
- Use DLAA instead if you already hit your cap and want maximum image quality.
- Drop to Balanced at 1080p only if you still need frames.
For which upscaler to pick, see DLSS vs FSR vs XeSS for Gaming.
Best settings by goal
Smoother Lower City on a CPU-limited PC
- Cap FPS to the city-sustainable rate; accept a lower locked number
- XMP/EXPO on, game on SSD, background apps closed
- God Rays off, Cloud Quality low
Cleaner high-refresh setup for Acts 1–2
- DLSS/FSR Quality with Model Quality and Detail Distance Medium
- higher cap your GPU holds in the wilds, still locked to avoid city spikes
Windows-side checks worth doing
- Install Baldur’s Gate 3 on an NVMe SSD with 15–20% free space.
- Use the correct discrete GPU on laptops and set a high-performance power mode.
- Update chipset and GPU drivers — CPU scheduling and driver overhead both affect Lower City frame times.
- Prefer the DirectX 11 renderer if the Vulkan option stutters on your system, or vice versa — test both, they perform differently per PC.

The best Baldur’s Gate 3 settings accept that Lower City is CPU-bound and optimize for it: cap your FPS to a rate the CPU can hold, turn God Rays off, drop the heavy sliders to Medium, enable XMP/EXPO, and run from an SSD. Steady frame times feel far smoother than a high number that collapses the moment you step into a crowd — no new GPU required.
Frequently asked questions
What settings give the most FPS in Baldur's Gate 3?
Set Model Quality and Detail Distance to Medium, Shadow Quality to Medium, turn Cloud Quality and God Rays down, and use DLSS or FSR on Quality. But the biggest single change for the Act 3 / Lower City drops is capping your frame rate, because that area is CPU-bound and no graphics slider fixes a CPU bottleneck. Out in earlier acts the graphics settings raise FPS normally.
Why does Baldur's Gate 3 drop FPS in Act 3 / Lower City?
Baldur's Gate 3 drops frames in Lower City because Act 3 simulates a dense, crowded urban zone with many NPCs and systemic AI, which overloads the CPU no matter how strong your graphics card is. Lowering graphics settings barely helps there because the GPU is not the bottleneck. The fix is to reduce CPU load — cap your frame rate, enable XMP/EXPO, run from an SSD, close background apps — so frame times stay flat in the busiest streets.
Should I use DLSS or FSR in Baldur's Gate 3?
Yes, use DLSS on Quality if you have an RTX card, or FSR on Quality otherwise. Baldur's Gate 3 is GPU-bound in the wilderness of Acts 1 and 2, so upscaling gives a solid FPS boost with little clarity loss at 1440p and 4K. It helps less in the CPU-bound Lower City, where a stable frame cap matters more, but there is no reason to turn it off — leave it on Quality across the whole game.
What is a good FPS cap for Baldur's Gate 3?
Cap to a rate your CPU can hold in Lower City, often 60 FPS on a strong CPU or 45 FPS on an older one. A steady 60 with flat frame times feels far smoother than an FPS that swings from 120 in camp to 50 in the city. Capping removes the sharp dips that read as stutter even when the average looks fine. Use RTSS or the in-game frame limiter to lock it.
Does a better GPU fix Baldur's Gate 3 performance?
Not in Act 3. Baldur's Gate 3 becomes CPU-bound in the crowded Lower City, so a stronger graphics card does little to raise frame rates there — a faster CPU with good single-thread performance and fast RAM matters more. A better GPU does help in Acts 1 and 2 and at 4K. For the Lower City drops most players complain about, focus on CPU headroom, XMP/EXPO memory, and a stable frame cap.
