Performance Optimization

Get the best performance from Provenance across all systems and devices

Provenance is highly optimized for Apple devices, but performance can vary based on your device, the emulated system, and your settings. This guide helps you get smooth, full-speed emulation across all 38+ supported systems.

Quick Performance Checklist

✅ 5-Minute Performance Boost:

1. Close background apps - Double-tap Home, swipe up to close

2. Disable visual effects - Settings → Turn off Smoothing and CRT filters

3. Use recommended cores - See per-system recommendations below

4. Enable Low Power Mode - For longer gaming sessions (slight performance trade-off)

5. Update to latest version - Performance improvements in every release

Understanding Performance

What Affects Performance?

Device Age (Most Important):

• 📱 iPhone 7 or newer - Full speed for all systems up to PlayStation/N64

• 📱 iPhone 6 or older - Good for 8-bit and 16-bit systems, struggles with 3D

• 📱 iPad Air 2 or newer - Excellent for all supported systems

• 📺 Apple TV 4K - Best performance, especially for demanding systems like Dreamcast

Emulated System Complexity:

• 🟢 Easy: NES, Game Boy, SNES, Genesis (full speed on any device)

• 🟡 Moderate: GBA, PlayStation, N64 (requires iPhone 6s or newer)

• 🔴 Demanding: Dreamcast, PSP (requires iPhone 11 or newer / Apple TV 4K)

App Settings:

• ⚙️ Visual filters (Smoothing, CRT) add processing overhead

• ⚙️ Save states can cause brief frame drops when created

• ⚙️ Audio sync affects timing accuracy vs performance

• Use save states instead of in-game saves (faster loading)

---

Portable Systems

Game Boy Advance

Performance: ✅ Full speed on iPhone 6s and newer

Tips:

• Core: Use "mGBA" core (most accurate, good performance)

• Alternative: "VBA-M" core for older devices (slightly faster)

• Battery: GBA games drain battery faster than GB/GBC (3D effects)

Optimization:

• Disable "Solar Sensor" if not using Boktai games (saves CPU)

Nintendo DS

Performance: ⚠️ Requires iPhone 8 or newer for full speed

Tips:

• 3D games (Mario 64 DS, Mario Kart DS) need iPhone 11+ for smooth play

• 2D games (Pokémon, Advance Wars) run well on iPhone 8-10

• Screen layout: Vertical layout recommended (one screen above the other)

Optimization:

• Lower internal resolution in settings (3x → 2x)

• Disable "High-Res 3D" for 3D games

PSP

Performance: 🔴 Requires iPhone 11 or newer

Tips:

• Most demanding system in Provenance

• Works best on iPhone 12 Pro or newer with active cooling

• Apple TV 4K recommended for best experience

Optimization:

• Set frameskip to "Auto" or "1" if needed

• Lower internal resolution to 2x (still looks great)

• Disable texture filtering if slow

• Close all background apps

3D Systems

Nintendo 64

Performance: 🟡 Full speed on iPhone 7 and newer

Tips:

• Multiple cores available: "Mupen64Plus" (recommended) and "ParaLLEl"

• ParaLLEl core: Better accuracy, requires iPhone 11+ for full speed

• Mupen64Plus: Faster, works on older devices

Game-Specific:

• ✅ Works great: Super Mario 64, Ocarina of Time, Mario Kart 64

• ⚠️ Needs newer device: Perfect Dark, Conker's Bad Fur Day, Donkey Kong 64

• ❌ Problematic: GoldenEye 007 (slowdown even on newest devices)

Optimization:

• Use "Rice" video plugin for older devices (faster but less accurate)

• Disable "widescreen hack" for performance

• Lower resolution multiplier: 2x → 1x (native N64 resolution)

PlayStation

Performance: ✅ Full speed on iPhone 7 and newer

Tips:

• Best core: "PCSX-ReARMed" (excellent compatibility + speed)

• CHD support: Multi-disc games work great in CHD format (faster loading)

Game-Specific:

• ✅ Perfect: Final Fantasy VII-IX, Crash Bandicoot, Spyro, Metal Gear Solid

• ⚠️ May need frameskip: Ridge Racer Type 4, Gran Turismo 2

Optimization:

• Use CHD format instead of BIN/CUE (20-40% smaller, faster)

• Enable "Enhanced Resolution" on iPhone 11+ (sharper graphics, minimal performance hit)

Dreamcast

Performance: 🔴 Requires iPhone 11 or newer

Tips:

• Use Reicast core

• Apple TV 4K recommended for best experience

• Not all games are compatible (core still in development)

Game-Specific:

• ✅ Works well: Sonic Adventure, Crazy Taxi, Soulcalibur

• ⚠️ Slow/buggy: Shenmue, Jet Set Radio

• ❌ Incompatible: Some titles don't boot

Optimization:

Advanced Optimization

Battery Life vs Performance

Best Battery Life:

1. ✅ Enable Low Power Mode (Settings → Battery)

2. ✅ Lower screen brightness (biggest battery drain)

3. ✅ Play 8-bit/16-bit systems (NES, SNES, GB, Genesis)

4. ✅ Use wired headphones (Bluetooth drains faster)

5. ✅ Disable background app refresh for Provenance

Battery Impact by System:

• 🟢 Low drain: NES, GB, GBC, SNES, Genesis (~4-6 hours)

• 🟡 Moderate: GBA, PlayStation (~3-4 hours)

• 🔴 High drain: N64, Dreamcast, PSP (~2-3 hours)

Visual Quality vs Performance

Maximum Quality (iPhone 11+ recommended):

• ✅ Smoothing filter ON

• ✅ CRT filter ON

• ✅ Enhanced resolution (PlayStation, N64)

• ✅ Shader effects (specific cores)

Balanced (iPhone 7-10):

• ⚙️ Smoothing: OFF

• ⚙️ CRT filter: OFF

• ⚙️ Enhanced resolution: ON (PlayStation only)

Maximum Performance (iPhone 6 and older):

• ❌ All filters OFF

• ❌ Native resolution only

• ❌ Frameskip: Auto

Recommended Cores by System

When multiple cores are available, these are the best performance/compatibility balance:

System	Recommended Core	Alternative	Notes
Genesis	Genesis Plus GX	PicoDrive	Plus GX = better accuracy
SNES	Snes9x	bsnes	Snes9x = faster
GBA	mGBA	VBA-M	mGBA = best accuracy
N64	Mupen64Plus	ParaLLEl	ParaLLEl needs iPhone 11+
PlayStation	PCSX-ReARMed	Beetle PSX	ReARMed = faster

Troubleshooting Performance Issues

Game is Slow or Stuttering

Symptoms: Framerate drops, audio crackling, sluggish controls

Solutions (try in order):

1. ✅ Close background apps

   • Double-tap Home button

   • Swipe up on all apps except Provenance

2. ✅ Disable visual filters

   • Provenance Settings → Smoothing: OFF

   • Provenance Settings → CRT Filter: OFF

3. ✅ Check core selection

   • In-game menu → Core Info

   • Try alternative core if available

4. ✅ Lower internal resolution

   • Settings → Video → Resolution Multiplier: 1x or 2x

5. ✅ Enable frameskip

   • Settings → Frameskip: Auto

6. ✅ Restart device

   • Power off → Wait 10 seconds → Power on

Specific Game is Slow, Others Are Fine

Cause: Game-specific compatibility or CPU-intensive content

Solutions:

1. Check online compatibility lists for that core

2. Try alternative ROM dump (bad ROM = poor performance)

3. Some games are just demanding (GoldenEye 007, Conker, etc.)

4. Update to latest Provenance version (cores improve over time)

Audio Crackling or Popping

Cause: CPU can't keep up with audio buffer

Solutions:

1. Enable frameskip (lets audio stay smooth)

2. Close background audio apps (Music, Spotify)

3. Disable Bluetooth audio (use wired headphones)

4. Lower in-game audio settings if available

Performance Got Worse After Update

Cause: New settings default, cache issue, or regression

Solutions:

1. Check if new visual settings were enabled automatically

2. Delete and reinstall Provenance (backup saves first!)

3. Report regression on GitHub Issues

Tips from the Community

From Discord/Reddit/App Store reviews:

1. 💡 "Airplane mode improves battery life by 30%" - Disables background sync

2. 💡 "CHD format loads 2-3x faster than BIN/CUE" - Especially for multi-disc PlayStation games

3. 💡 "Close Music app before playing" - Prevents audio interference

4. 💡 "Delete old save states" - Too many save states can slow library loading

5. 💡 "Use iPad for PSP games" - Bigger screen + better cooling = smoother performance
