INTEL ARC · GPU SWAP & SMOOTHNESS CHEATSHEET

01 PRE-SWAP CHECKLIST

Before You Remove the Old GPU

Download the latest Intel Arc driverGet it from intel.com/download-center — WHQL version recommended. Save the .exe to a known location.

Download DDUDisplay Driver Uninstaller from guru3d.com — essential for clean driver swap between vendors.

Note current display settingsResolution, refresh rate, HDR config, VRR state. These may reset after swap.

Disable Resizable BAR check (if needed)Arc GPUs require ReBAR for best performance. Verify it's enabled in BIOS — most modern boards have it on by default.

Critical: ReBAR Requirement

Intel Arc GPUs lose significant performance without Resizable BAR (up to 10-15% in some titles). Unlike NVIDIA/AMD where it's optional, ReBAR is strongly recommended for Arc.

BIOS → Advanced → PCI Subsystem → Above 4G Decoding: Enabled
BIOS → Advanced → PCI Subsystem → Resizable BAR: Enabled
Verify with GPU-Z: Bus Interface → Resizable BAR should say Enabled

WARN AMD Ryzen + Intel Arc: ensure CSM is disabled in BIOS for ReBAR to work.

02 CLEAN DRIVER INSTALL

DDU → Intel Driver Procedure

Boot into Safe ModeWin+R → msconfig → Boot → Safe boot ✓ → Restart. Or: Shift + Restart → Troubleshoot → Startup Settings → 4.

Run DDUSelect GPU vendor of OLD card (NVIDIA/AMD/Intel). Click 'Clean and restart'. If switching vendors, run DDU twice — once for old vendor, once for Intel.

Shut down, swap GPUPower off completely. Remove old GPU, install Intel Arc card. Connect power cables (8-pin for A770/B580).

Boot and install Intel driverWindows will use basic display. Run the Intel driver .exe downloaded earlier. Allow firmware updates when prompted — Arc updates FW components with driver installs.

Restart 2-3 timesIntel Arc may need multiple restarts for firmware + driver to fully initialize. Intel Graphics Software may show incomplete info on first boot — normal behavior.

INFO Intel driver installs include multiple firmware components (FW, OPROM, FWData, Config) — this is normal and different from NVIDIA/AMD which use a single BIOS.

03 POST-INSTALL TUNING

Intel Graphics Software Settings

SET Display → Refresh Rate: Max (e.g. 144Hz)
SET Display → Variable Refresh Rate: Enabled
SET Graphics → Low Latency Mode: Enabled
TIP Graphics → FPS Limiter: set 3-5 below monitor max if using VRR
CHECK System Info → Resizable BAR: Enabled

Windows Settings

SET Game Mode: On
SET Hardware-accelerated GPU scheduling: On
TIP Power Plan: High Performance or Ultimate Performance
WARN Disable 'Fullscreen Optimizations' on old DX9/DX11 games that stutter

Shader Cache Warmup

Intel Arc shader compilation can cause stutter on first launch of games. The Precompiled Shader Distribution system helps, but you should still:

Let games fully compile shaders on first launch (progress bars in menus)
Run a quick benchmark pass in-game before judging performance
DX12/Vulkan titles handle this much better than DX11 on Arc

INFO DX11 performance has improved dramatically since Alchemist launch (~19% avg FPS gain over early drivers) but DX12 remains the sweet spot for Arc.

04 XeSS & FRAME GENERATION TUNING

XeSS Super Resolution Modes

Mode	Scale	Best For
Ultra Quality	1.3x	Minimal upscaling, max clarity
Quality	1.5x	Recommended default — best balance
Balanced	1.7x	Good for GPU-limited scenarios
Performance	2.0x	Max FPS boost with some quality loss
Ultra Performance	3.0x	Extreme boost, noticeable artifacts

XeSS Frame Generation / MFG

Mode	Ratio	Notes
XeSS-FG (XeSS 2)	1:1	1 generated frame per rendered. Low latency impact.
MFG 2x (XeSS 3)	2:1	2 generated per rendered. Good balance.
MFG 3x (XeSS 3)	3:1	3 generated per rendered. Higher latency.
MFG 4x (XeSS 3)	4:1	Max smoothness. Only for slow-paced games.

WARN XeSS-FG requires XeLL (Xe Low Latency) enabled. MFG only works in DX12 titles on Windows. Game restart required to change MFG mode.

Driver Override for MFG

You can force MFG on any XeSS 2 game even if the game doesn't natively support it:

Open Intel Graphics Software → Graphics tab
Find Multi-Frame Generation override section
Select 2x / 3x / 4x mode
Launch game → restart required for changes

TIP Available on ALL Arc GPUs — Alchemist, Battlemage, and even iGPUs with XMX units (Meteor Lake, Lunar Lake, Arrow Lake, Panther Lake).

05 SMOOTHNESS & FRAME PACING

Frame Pacing Optimization

VRR Enable FreeSync/Adaptive Sync in display settings — Arc supports both
CAP Set FPS limiter in Intel Graphics Software 3-5 fps below refresh rate
API Prefer DX12/Vulkan over DX11 — Arc's DX12 path is significantly better optimized
STUTTER First-run shader stutter is expected — goes away after initial compilation

Monitoring Smoothness

Use Intel PresentMon or CapFrameX to check smoothness:

Frametime — total time per frame (lower = better)
GPU Busy — time GPU actively renders (Intel-exclusive metric)
Frametime ≈ GPU Busy → GPU-limited (ideal)
Frametime >> GPU Busy → CPU-bottlenecked

TIP PresentMon's GPU Busy metric is the best way to determine if you're CPU or GPU limited — far more precise than simple GPU utilization %.

Known Arc-Specific Issues

Issue	Workaround
DX9 games stutter/crash	Use DXVK (DX9→Vulkan wrapper)
Shader stutter on first run	Wait for Precompiled Shaders, run benchmark first
Missing game in Intel GS profiles	Add .exe manually → set per-game settings
Afterburner OSD not showing	Use PresentMon overlay instead, or update RTSS
No memory OC option	Intel Graphics Software now supports VRAM OC on Battlemage

06 QUICK OC GUIDE

Arc Overclocking Basics

Start with +50 MHz GPU offsetIntel Graphics Software → Performance → GPU Clock Offset. Test stability with 3DMark Time Spy.

Increase in +25 MHz stepsRun benchmark after each step. Watch for artifacts, crashes, or driver timeouts (TDR).

Adjust voltage if neededMax safe software voltage ~1.18-1.2V on Alchemist. Beyond requires hardware mod (EVC2). Battlemage may differ.

VRAM OC (Battlemage)B580: stock 19 Gbps, OC possible up to ~22 Gbps via Intel Graphics Software. Memory OC not available on Alchemist.

Power limit: raise to max availableIntel Graphics Software allows PL increase. For higher limits on Acer BiFrost cards, use BiFrost software profiles.

WARN Reset to defaults via Intel Graphics Software if unstable. Arc OC Tool's only reset method is through Arc Control/Graphics Software.

07 ARC STRENGTHS & CONSIDERATIONS
