F125 stuttering fix
Learn about F125 stuttering fix
Updated October 21, 2025
If F1 25 is freezing for a split second, hitching during corners, or feeling choppy even with high FPS, you’re not alone. That’s exactly what players mean by F125 stuttering. This F125 stuttering fix guide shows you, step by step, how to stabilize frametimes and make the game feel smooth and predictable again.
Quick Answer
Most stutters in F1 25 come from unstable frametimes (not just low FPS). Update GPU drivers, switch to Exclusive Fullscreen, disable overlays, turn off ray tracing, set a single frame cap 2–3 FPS below your monitor’s refresh, and reduce CPU‑heavy settings (Crowd, Shadows, Mirrors). If you use a wheel, set its USB polling to 500 Hz.
Why F125 stuttering fix Feels So Hard at First
You’re doing everything “right” but the game still hiccups right as you turn in—frustrating. In F1 25, tiny scheduling spikes from your CPU, background overlays, ray tracing, or USB devices can cause inconsistent frametimes. The fix is less about chasing maximum FPS and more about eliminating the sources of those spikes.
By the end of this guide, you’ll know how to build a clean baseline, pick the right caps and settings, and systematically remove stutter—even on mid‑range PCs.
What F125 stuttering fix Actually Means in F1 25
- Stutter: micro-hitches where the image pauses briefly. Often >10–20 ms frametime spikes.
- Low FPS: consistently low frames, but smooth motion. Different problem.
- Tearing: horizontal breaks without V‑Sync/VRR; not the same as stutter.
- Online lag: network latency; can feel like stutter but has different causes.
F1 25 can stutter from:
- CPU spikes (crowds, weather, mirrors, physics, wheel drivers)
- GPU spikes (ray tracing, shadows, mirrors, replays)
- Overlays and background apps (Discord, EA/Steam overlays, GPU recorders)
- Uncapped frames or multiple caps fighting each other
- First‑run shader compilation or installing on a slow drive
Before You Start (Prerequisites)
- Platform: PC on the latest F1 25 patch (Steam or EA App). Console tips included in Troubleshooting.
- Update: Latest NVIDIA/AMD/Intel graphics driver and Windows updates.
- Hardware:
- If using a wheel, update firmware and have its control panel open (Fanatec/Fanatec Control Panel, Logitech G HUB, Thrustmaster Control Panel, Moza Pit House, etc.).
- Headset/mic software closed if not needed.
- Test mode:
- Use Time Trial at Bahrain or Austria (clear visibility; low AI load).
- Optional: Run the built‑in benchmark if your copy includes it.
- Menus you’ll use in-game:
- Settings > Graphics (Video Mode and Advanced)
- Settings > Game Options > Telemetry (if you use SimHub/third‑party apps)
- Windows/NVIDIA/AMD panels:
- Windows Settings > System > Display > Graphics > Default graphics settings
- NVIDIA Control Panel or AMD Software: per‑game profile for F1 25
Step-by-Step: How to Fix / Improve F125 stuttering fix
- Update and reboot
- Install the latest GPU driver (clean install if you’ve had issues).
- Reboot your PC after the driver install.
- Move the game to an SSD (if not already)
- Streaming from an HDD can cause hitches. Put F1 25 on a fast SSD/NVMe.
- Kill overlays and background recorders
- Disable: Discord overlay, Steam overlay, EA App overlay, GeForce Experience overlay/Instant Replay, AMD ReLive, Xbox Game Bar capture.
- Close RGB and peripheral software you don’t need while driving.
- Windows graphics housekeeping
- Go to Settings > System > Display > Graphics > Default graphics settings:
- Game Mode: On
- Variable Refresh Rate (VRR): On (if your monitor supports it)
- Hardware‑accelerated GPU scheduling (HAGS): Try On first. If stutter persists later, try Off (you must restart after changes).
- Settings > System > Power: set Power Mode to Best Performance.
- Settings > System > Display > Graphics > Browse/add F1 25:
- Set it to High Performance (discrete GPU).
- NVIDIA/AMD control panel (per‑game profile)
- Use defaults where possible; only change the following:
- Power management: Prefer maximum performance (NVIDIA) / Default/Maximize Performance (AMD).
- Low Latency: On (or Ultra) if you are NOT using the game’s Reflex/Anti‑Lag. If you enable Reflex/Anti‑Lag in-game, keep driver Low Latency to Off/Default to avoid conflicts.
- Vertical Sync: Off here (we’ll control it in-game/with VRR).
- G‑SYNC/FreeSync: On in the monitor OSD and in the driver.
- Set a clean in-game baseline
- Launch F1 25 > Settings > Graphics > Video Mode:
- Display Mode: Exclusive Fullscreen (if available).
- Resolution: Native.
- V‑Sync: Off (VRR users) or On (if you don’t have VRR).
- Frame Rate Limit: On. Set to 2–3 FPS below your monitor refresh
- 144 Hz monitor: cap at 141
- 240 Hz: cap at 237
- 60 Hz: cap at 58
- Settings > Graphics > Advanced Setup:
- Upscaler: Start with TAA or your GPU vendor’s upscaler without Frame Generation. We’ll test FG later.
- Ray Tracing: Off for baseline.
- Motion Blur: Off (blur can mask issues; we want to see frametime behavior).
- Dynamic Resolution: Off.
- Shadows: Medium
- Mirrors: Low or Medium
- Reflections: Medium
- Crowd: Low or Medium
- Weather Effects/Particles: Medium
- Anisotropic Filtering: 8x or 16x (cheap; keep quality).
- Try to keep the baseline modest. We’ll raise later if smooth.
This is the screen where you see “Video Mode” on the left and “Advanced Setup” on the right, with each setting listed and small preview thumbnails. Ensure your changes apply and the Frame Rate Limit shows your custom value.
- Build the shader cache
- Go into Time Trial (Bahrain/Austria).
- Drive 3–5 laps. First laps might have small hitches; they should lessen as shaders compile.
- Pick one frame limiter—only one
- Use the in‑game Frame Rate Limit OR RTSS OR driver Max Frame Rate. Do not stack multiple limiters.
- Recommendation: in‑game limiter for simplicity, RTSS only if you know frametime tuning.
- If you have a wheel, reduce USB polling
- Many wheels default to 1000 Hz, which can cause CPU spikes in some systems.
- In your wheel software:
- Set USB/HID polling to 500 Hz (or 250 Hz).
- Update wheelbase and pedal firmware.
- Replug into a motherboard USB port (avoid front-panel hubs if possible).
- Optional: Test Frame Generation (FG) carefully
- In Settings > Graphics > Upscaling/Frame Generation:
- Turn on your GPU’s Frame Generation (if supported).
- Keep your frame cap enabled and still below monitor refresh.
- Enable Reflex/Anti‑Lag in-game if available (and disable driver Low Latency to avoid conflicts).
- Note: FG smooths motion but does not fix CPU hitches. If FG adds judder or input latency, turn it off.
- Tune CPU‑heavy settings first
- If you still see stutters, drop:
- Crowd to Low
- Shadows to Low/Medium
- Mirrors to Low
- Weather Effects to Low/Medium
- Reflections to Low/Medium
- Keep eye candy like Texture Quality high if VRAM allows; it’s not very CPU heavy.
- Test ray tracing last
- Turn on a single RT feature at a time (e.g., RT Reflections).
- Do 2–3 laps. If frametime spikes return, disable RT or lower RT quality.
- Ray tracing is a common stutter source on mid‑range rigs.
- Toggle HAGS if needed
- If stutter persists: switch HAGS to the opposite state from step 4 and restart Windows. Some systems prefer HAGS Off.
- Rebuild the game’s hardware settings (only if needed)
- Close the game.
- Go to your Documents\My Games\F1 25\hardwaresettings folder.
- Rename the config file (commonly named hardware settings file) to .old and restart the game to regenerate it.
- Re‑apply your settings.
- Final check with AI/Weather
- Test a 5‑lap race with 20 AI at Bahrain.
- Test a short wet session (rain is heavier on CPU/GPU).
- Raise settings slowly if everything is smooth.
You should now feel consistent motion with no micro-pauses, stable steering feedback, and a frame time graph (if you use one) without big spikes.
Common Mistakes and Myths About F125 stuttering fix
- Maxing FPS instead of stabilizing frametimes: A steady 120 FPS beats a spiky 170.
- Enabling multiple limiters (in‑game + RTSS + driver): causes pacing conflicts.
- Turning on every ray tracing option “because my FPS is high”: FPS can be high while frametime still spikes.
- Thinking Frame Generation fixes stutter: it improves perceived smoothness but won’t fix CPU hitches.
- Leaving overlays on: even one overlay can introduce random hitches.
- Ignoring wheel polling: 1000 Hz can overload weaker CPUs in busy scenes.
Troubleshooting and “What If It Still Feels Wrong?”
Stutter only online
- Likely cause: network variability or netcode. Action: test offline/Time Trial; if smooth offline, lower your frame cap a bit more for headroom, use wired Ethernet, and close bandwidth-hungry apps.
Stutter at race starts or safety car
- Likely cause: CPU load spikes with all cars visible. Action: lower Crowd, Shadows, Mirrors; keep RT off; use a slightly lower frame cap for headroom.
Smooth in dry, stutters in rain
- Likely cause: extra particles/reflections. Action: reduce Weather Effects/Particles and Reflections; consider disabling RT.
Only when recording/streaming
- Likely cause: encoder overhead or disk writes. Action: use NVENC/AV1 hardware encoding, set a CQP/quality target over CBR, record to an SSD, and keep one frame limiter (prefer in‑game).
VRR/G‑SYNC feels “jittery”
- Likely cause: no frame cap or double V‑Sync. Action: VRR On, V‑Sync Off, single frame cap 2–3 FPS below refresh. Don’t enable V‑Sync in driver and game together.
Changes don’t stick
- Note: Make sure you hit Apply/Save on the Graphics screen. If settings still revert, regenerate the hardware settings file (see Step 14) and verify game files in Steam/EA App.
Wheel FFB “lags” when stutter occurs
- Likely cause: CPU contention. Action: set wheel polling to 500 Hz, close telemetry apps temporarily, reduce AI count to test, lower CPU‑heavy graphics options.
Console (PS5/Xbox) stutter
- Use Performance mode, enable VRR on a compatible display, fully close background apps, and power cycle the console. If issues persist, reinstall on internal SSD and avoid recording overlays.
What NOT to do
- Don’t stack three different frame limiters.
- Don’t enable all ray tracing options at once.
- Don’t leave Instant Replay/Shadowplay running while diagnosing.
- Don’t chase ultra‑high FPS caps; prioritize stable frametimes.
Pro Tips Once You’re Comfortable
- Per‑track presets: Save a “Wet/AI Heavy” preset with lower Crowd/Shadows/Mirrors for Monaco/Singapore and rain.
- RTSS fine-tuning: If you know RTSS, a scanline or 0.01 ms limiter can yield ultra‑smooth pacing—just ensure nothing else limits FPS.
- Telemetry apps: If you use SimHub or dash apps, increase their update interval slightly to reduce CPU load.
- Exclusive Fullscreen: Stick with it for the most consistent VRR and input latency on many systems.
How to Know It’s Working (Definition of Done)
Run these quick checks:
- Time Trial, 5 laps at Bahrain: no hitches on corner entry/exit.
- 5‑lap race with 20 AI: race start is smooth, cameras/cutscenes don’t spike hard.
- Wet session test: motion remains consistent; no periodic micro‑pauses.
- Input feel: steering is predictable; no sudden heaviness when cars bunch up.
- Optional: Frametime graph shows a nearly flat line with no large spikes.
If you pass these, your F125 stuttering fix is dialed in.
