Drivers, DLSS/FSR, thermals, undervolting basics, and settings that actually work
Max FPS isn’t about one “magic tweak.” It’s about removing bottlenecks without cooking your laptop or turning it into a jet engine. The safe approach is: stable drivers → clean power settings → controlled thermals → smart upscaling → sane in-game settings.
This guide walks through the exact steps I use to get higher FPS and smoother gameplay without risky mods.
Before You Start: What “Safely” Means
✅ Safe: driver updates, settings tweaks, airflow improvements, FPS caps, mild undervolting (where supported), monitoring temps
⚠️ Higher risk: BIOS mods, extreme overclocks, disabling safety limits, aggressive undervolting without testing
❌ Not recommended: anything that removes thermal protections or pushes voltage beyond normal tools
Step 1: Establish a Baseline (Don’t Optimize Blind)
- Pick one game you actually play (or a built-in benchmark game)
- Record:
- Average FPS
- 1% lows (smoothness)
- GPU temp + CPU temp
- GPU usage %
- Use simple monitors:
- MSI Afterburner + RivaTuner (overlay), or your GPU software overlay
Why: You need to know if you’re GPU-bound (GPU at ~95–99%) or CPU-bound (GPU underutilized, CPU hot/spiking). The fixes differ.
Step 2: Update Drivers the Right Way (Stable > Newest)
A) GPU Drivers
- NVIDIA: use NVIDIA App / GeForce Experience
- AMD: use Adrenalin
- Intel: Intel Driver & Support Assistant (or laptop OEM)
Best practice:
- If you’re not having issues: update every few months.
- If you are having stutters/crashes: do a clean install.
B) Chipset + BIOS + Laptop Control App
- Update chipset drivers and your laptop’s control center (for power/fans).
- BIOS updates can improve stability and performance, but only update if:
- It mentions performance/thermal stability fixes, or
- You have known issues.
C) Optional: Clean driver install (only when needed)
If performance is weird or you swapped major driver branches:
- Use “clean install” option in the installer
- Or use DDU (Display Driver Uninstaller) carefully (advanced users)
Step 3: Windows Settings That Actually Boost FPS
A) Set Power Mode correctly (plugged in)
Settings → System → Power & battery
- Power mode: Best performance (when gaming plugged in)
B) Turn on Game Mode
Settings → Gaming → Game Mode → On
C) Graphics settings (important)
Settings → System → Display → Graphics
- Add your game → Options → set to High performance (forces dGPU)
D) Hardware-accelerated GPU scheduling (test it)
Settings → System → Display → Graphics → Default graphics settings
- HAGS: try On
If you see stutters or worse 1% lows, turn it Off. (This setting is hit-or-miss.)
E) Disable unnecessary overlays
Overlays can hurt 1% lows:
- Discord overlay, Xbox Game Bar overlay, multiple capture overlays at once
Step 4: Thermals = FPS (This Is Where Most Gains Come From)
A gaming laptop that runs hot will throttle, and throttling destroys FPS and smoothness.
A) Basic airflow (free FPS)
- Put the laptop on a hard, flat surface
- Clean the vents
- Lift the rear slightly (even a small stand helps)
B) Set an aggressive fan profile (plugged in)
In your laptop control app:
- Use Performance/Turbo mode for gaming
- Or create a curve that ramps earlier
Target: keep sustained temps stable so clocks don’t bounce.
C) Clean dust (big difference)
If your laptop is older or temps are climbing over time:
- Clean intakes/exhausts
- Consider internal cleaning if you’re comfortable (or have a shop do it)
D) Repaste? (advanced but huge)
Only if your laptop is older and throttling badly:
- A quality repaste can reduce temps significantly
- Not required for most users, but it’s one of the biggest thermal improvements.
Step 5: DLSS / FSR / XeSS (The “Smart” FPS Boost)
Upscaling often gives the best FPS gain per effort.
What to use
- NVIDIA: DLSS
- AMD/any GPU: FSR (FSR works on NVIDIA too)
- Intel/any GPU: XeSS (works best on Intel but can run elsewhere)
Recommended starting point
- 1080p: use Quality mode first
- 1440p/1600p: Quality or Balanced depending on the game
Frame Generation (if available)
- Great for boosting FPS feel, but it can add a bit of latency.
- Use it more for story games than competitive shooters.
Step 6: In-Game Settings That Give the Biggest FPS Per Visual Cost
If you want max FPS, don’t randomly drop everything—hit the “expensive” settings first.
High impact (lower these first)
- Shadows (huge FPS cost)
- Volumetrics / fog
- Ray tracing (biggest performance hit)
- Screen-space reflections
- Ambient occlusion
- Crowd density / simulation settings (CPU-heavy in some games)
Low impact (keep these higher if you want)
- Textures (unless VRAM is limited)
- Anisotropic filtering
- Anti-aliasing (depends—DLSS can replace it)
Competitive preset (fast + clear)
- Textures: Medium/High
- Shadows: Low
- Volumetrics: Low/Off
- Reflections: Low
- Motion blur: Off
- Film grain: Off
- FPS cap: match display target (120/144/165)
Step 7: FPS Caps Are Not “Lower Performance”—They Prevent Throttling
Capping FPS can increase average FPS stability and improve 1% lows by reducing heat spikes.
Good caps:
- Story games: 60–90 FPS
- Competitive: 120–165 FPS (depending on your screen)
Where to cap:
- In-game limiter (best)
- NVIDIA Control Panel / AMD Adrenalin
- RTSS (very consistent)
Step 8: Undervolting Basics (Safe Approach)
Undervolting can reduce heat and increase sustained clocks—but only if your platform supports it.
A) GPU undervolting (common and effective)
- NVIDIA: MSI Afterburner curve editor
- Goal: same FPS at lower voltage → lower temps → less throttling
Safe method:
- Make small changes
- Stress test (10–20 minutes)
- If stable, keep it
- If crashing/artifacts, back off
B) CPU undervolting (platform dependent)
Many modern laptops restrict CPU undervolting in BIOS/firmware. If it’s supported:
- Use reputable tools and small steps
- Test stability thoroughly
Safety rule: undervolt to reduce temps—not to chase unstable clocks.
Step 9: RAM + Storage Tweaks That Matter
A) Dual-channel RAM (big for 1% lows)
If your laptop supports upgrades:
- Dual-channel (2 sticks) often improves smoothness and some FPS.
B) SSD health and free space
- Keep 15–20% free space
- Make sure the game is on the SSD (not slow external storage)
Step 10: Quick Troubleshooting (When FPS Still Feels Bad)
Symptom: High temps + FPS drops after 10–15 minutes
- That’s throttling → increase fans, improve airflow, repaste (advanced)
Symptom: GPU usage is low (60–80%) while FPS is low
- Likely CPU bottleneck or wrong GPU selected
- Set game to “High performance” GPU; lower CPU-heavy settings (crowds, view distance)
Symptom: Stutters, but FPS looks high
- Check background apps, overlays, shader compilation, thermal spikes
- Cap FPS; disable extra overlays; let shaders finish compiling
Symptom: Great FPS plugged in, terrible on battery
- Normal behavior—gaming laptops reduce power on battery.
- For best results: play plugged in.
The “Best Safe FPS Recipe” (Short Version)
If you only do 7 things, do these:
- Set game to use High-performance GPU
- Use Best performance power mode while plugged in
- Turn on aggressive fan mode for gaming
- Enable DLSS/FSR (Quality first)
- Lower Shadows + Volumetrics + RT first
- Cap FPS to stabilize temps and 1% lows
- Monitor temps + usage to confirm you’re not throttling
