Intel Iris Xe is the integrated GPU in Intel's 11th, 12th, and 13th generation Core processors — released from 2020 onward. You will find it in the Dell XPS 13 (2021 and later), HP Spectre x360, Lenovo ThinkPad X1 Carbon 2021+, ASUS ZenBook 14, and most ultrabooks built around processors like the Core i5-1135G7, i7-1165G7, i5-1235U, and i7-1255U.

The Iris Xe has up to 96 execution units, compared to the older UHD 620's 24. In real-world Roblox performance, this translates to roughly 3–4x more frames. Where the UHD 620 struggles to hit 30 FPS in demanding games, the Iris Xe can reach 60 FPS with the right settings in most games.

It still shares system RAM with the CPU and has no dedicated video memory. The gains from the fixes below are real but more modest than on older Intel integrated graphics — you are already starting from a better position.

FPS by game

Game Default settings After optimization
Arsenal 42–58 FPS 60–75 FPS
Tower of Hell 45–60 FPS 60–80 FPS
Brookhaven RP 38–52 FPS 52–65 FPS
Pet Simulator 99 28–42 FPS 38–55 FPS
Adopt Me! 35–50 FPS 50–62 FPS

Check for a dedicated GPU first

Many laptops with Iris Xe also have a discrete NVIDIA or Intel Arc GPU. Open Device Manager → Display adapters. If you see two entries, you have a second GPU that Roblox is probably not using.

Fix it: Windows Settings → System → Display → Graphics → Add an app → add RobloxPlayerBeta.exe → Options → High performance. This routes Roblox to the dedicated GPU instead of the Iris Xe. If you have a dedicated GPU, do this first — it is more impactful than any of the settings below.

Optimization steps

1. Power plan: High Performance, plugged in. Press Win+R, type powercfg.cpl, press Enter. Select High Performance. The Iris Xe throttles on battery — you lose a noticeable amount of GPU and CPU clock speed. For extended gaming sessions, plug in and set High Performance.

2. Intel Graphics Command Center: Maximum Performance. Right-click desktop → Intel Graphics Command Center → System → Power → Gaming Power Plan → Maximum Performance. This unlocks the full TDP budget for the iGPU during gaming workloads.

3. Roblox graphics: Manual, Level 4–6. The Iris Xe can handle moderate quality settings. In Roblox, press Esc → Settings → Graphics Mode → Manual. Start at Level 4 and check your FPS. If you are above 55 FPS consistently, raise it. Shadows can usually stay on at Level 4 without much cost.

4. Disable fullscreen optimizations for Roblox. Press Win+R, type %localappdata%\Roblox\Versions. Open the newest version folder. Right-click RobloxPlayerBeta.exe → Properties → Compatibility → check "Disable fullscreen optimizations" → OK. Reduces input latency, no FPS downside.

5. Disable Xbox Game Bar and background recording. Press Win+I → Gaming → Xbox Game Bar → off. Then Gaming → Captures → turn off background recording.

Iris Xe vs older Intel integrated graphics

If you previously had a laptop with Intel UHD 620 and just got one with Iris Xe, the difference in Roblox is significant. Arsenal and Tower of Hell become playable at reasonable quality settings without reducing everything to minimum. Brookhaven and Adopt Me remain GPU-heavy games — their FPS depends heavily on how many players and props are loaded on screen.

The Iris Xe variant in 12th and 13th generation processors (Alder Lake / Raptor Lake) generally performs 10–15% higher than the 11th generation version at the same settings.
