The Intel UHD 620 is the integrated GPU in 8th and 9th generation Intel Core i3, i5, and i7 laptop processors. It ships in most Windows laptops sold between 2017 and 2021 — the Dell Inspiron 15 5000 series, HP Pavilion x360, Lenovo IdeaPad 3, Acer Aspire 5, and ASUS VivoBook 15 are all common examples.
It is not a gaming GPU. It has 24 execution units, shares system RAM with the CPU, and has no dedicated video memory. In a laptop with 8 GB of RAM, the UHD 620 takes roughly 1 to 1.5 GB of that for graphics, leaving less for Roblox, Windows, and everything else running in the background.
Roblox will run on the UHD 620, but default settings are not optimized for it. The Balanced power plan, background recording, and Roblox's automatic graphics mode all assume more headroom than you have. Each fix below removes a specific source of waste.
FPS by game
These are realistic ranges in a normal server. Your FPS will be closer to the low end of each range in a crowded server, closer to the high end in an empty one.
Check for a second GPU first
Some Intel laptops also have a dedicated NVIDIA or AMD GPU. If your laptop model number ends in H, HQ, or HK (for example, Core i7-8750H), open Device Manager and look under Display adapters. If you see two entries — an Intel UHD and a GeForce or Radeon — you have a dedicated GPU that Roblox is probably ignoring.
Fix that before doing anything else: Windows Settings → System → Display → Graphics → Add an app → add RobloxPlayerBeta.exe → Options → High performance. This one change can double your FPS if it applies to you.
If Device Manager only shows the Intel UHD 620, the steps below are the right path.
Optimization steps
1. Set your power plan to High Performance and plug in. Press Win+R, type powercfg.cpl, press Enter. Select High Performance. If you do not see it, click "Show additional plans." The UHD 620 clock speed drops significantly on battery and under the Balanced plan. You need High Performance AND the laptop plugged in to get the full rated speed.
2. Set Intel Graphics to Maximum Performance. Right-click your desktop. If you see "Intel Graphics Command Center," open it, go to System → Power → Gaming Power Plan → Maximum Performance. If you see "Intel HD Graphics Settings," click it → Power → On Battery → Maximum Performance. Intel limits iGPU clock speed by default to save power. This setting removes that limit.
3. Set Roblox graphics to Manual, Level 1 or 2. In Roblox, press Esc → Settings → Graphics Mode → Manual. Drag Graphics Quality to 1. Turn Shadows off. Roblox's automatic mode runs higher settings than the UHD 620 can maintain smoothly. Level 1 is not noticeably worse-looking at this GPU tier but is significantly more stable.
4. Turn off Windows visual effects. Press Win+R, type sysdm.cpl, press Enter. Click Advanced → Performance Settings → Adjust for best performance → OK. Window shadows, animations, and transparency all consume the same shared GPU memory as your game.
5. Disable Xbox Game Bar and background recording. Press Win+I → Gaming → Xbox Game Bar → turn off. Then Gaming → Captures → turn off background recording. The Game Bar video encoder uses GPU resources even when you are not recording.
6. Close Chrome, Discord, and Spotify completely. Hardware-accelerated Chrome tabs, Discord's video renderer, and Spotify's canvas all consume GPU. Minimizing them is not enough — close them. Press Ctrl+Shift+Esc, check for anything above 1% GPU in the processes list.
7. Keep the laptop on a hard, flat surface. The UHD 620 throttles when it overheats. Most budget laptops vent from the bottom. Playing on a bed, pillow, or lap blocks those vents and causes the GPU to clock down mid-game. A desk or lap desk makes a measurable difference in sustained FPS.
What these changes actually do
None of these steps modify Roblox files or require downloading anything. Every change is a Windows setting or a Roblox in-game option. The gains are real because you are removing things that were consuming your GPU's limited budget unnecessarily — not because you are unlocking hidden performance.
If your FPS after all of these steps is still below 30 in most games, your hardware is genuinely at its limit. The UHD 620 is not designed for gaming. The next step at that point is a hardware upgrade, not more settings tweaks.
