Stutter issue with Intel arc b580

[Techytech]

Bought a Intel Arc B580 to replace my RTX 4060 (8GB), but encountering frequent stuttering 1-2 FPS drops with vsync enabled at 60hz in the games I am currently playing PUBG,Red dead redemption 2,Hogwarts legacy and oblivion remaster with VSync enabled and with low settings to ensure no gpu bottleneck to blame for the issue I am experiencing. However two of the games I am currently playing GTA V and The Witcher 3 run very smooth on this card without any frequent 1-2 fps drops with vsync enabled at 1080p 60hz

Troubleshooting steps taken so far:
- Fresh Windows 11 Pro install with latest updates
- No startup or background applications running
- Latest and older Intel Arc drivers (using DDU for clean uninstalls)
- High-performance power plan enabled
- Rebar enabled
- Pci4 gen 4 enabled in bios

Given the absence of this issue on my nvidea RTX 4060 in the same system with those games, I suspect driver-related problems. I've reverted to my RTX 4060 8GB for now. I'd love to fix the Arc B580, but might consider selling if unresolved.

System specs:-
-CPU:intel i5 14400f
- Motherboard: MSI PRO B760M-E DDR4
- RAM: 16 GB (2 x 8 GB) KLEVV DDR4 3200 MHz
- Storage: 1 TB KLEVV CRAS C910 M.2 NVMe Gen 4 SSD
- Graphics (currently): RTX 4060 8GB (previously Intel Arc B580)
- Power Supply: MSI MAG A650BN 650W
- Monitor: Dell 2417HG 1080p 60Hz

Any insights or suggestions would be greatly appreciated!

...totally get how annoying those random stutters are.. especially when your old RTX 4060 ran smooth in the same setup... the fact that GTA V and Witcher 3 run fine on the Arc but PUBG, RDR2, and others don’t really points to driver game optimizations rather than your hardware. Intel’s been rolling out updates pretty quickly, so it could improve with future drivers. Couple of things worth checking when you’ve got time: Which Arc driver version are you on 101.xx or later makes a big difference. Is HAGS on or off in Windows? What render mode are the games using (DX11, DX12, Vulkan)? Any spikes in CPU/GPU usage when the stutters happen? (PresentMon or Afterburner can show this). Are you on HDMI or DisplayPort? (Sometimes matters with V-Sync).

One quick trick to try turn off V-Sync in-game and just lock your FPS to 60. Sometimes that smooths things out more than letting V-Sync handle it. I’d say hang onto the Arc a bit longer if you can, it’s got the horsepower, just needs better tuning for some titles. And hey, the more feedback like yours Intel gets, the faster those fixes land.

Hello there, and thank you for attempting to help.Can confirm that this is a driver issue. or gpu related issue I installed this exact same Arb B580 in a friend's computer because he was interested in acquiring one for his setup, and I mentioned the stuttering issue I was seeing with this GPU.So I suggested we test this GPU in his system to see if you are getting the same problem vsync enabled lowest graphics settings at 1080p 60hz vsync enabled.He also has a Dell monitor with no adaptive sync technologies, 1080p 60Hz.The issue persists, with regular drops of two to three frames each second.We then tested four different drivers, including the most recent, etc.His rig has greater specs than mine: i7 14700, 32GB ddr5, rebar enabled, xmp profile, and the same issue I'm having!

I disabled hags; no difference. Enabled again There's no difference

The stutter seems to be lined everytime some shader or asset loads.With a Frame cap at 60 and vsync enable and it seems like in game everytime when a new asset or shader loads in the fps drop it micro freez for a second .This does happens very frequently every two to three minutes.With vsync disabled and no frame cap the fps runs at 100fps then it will drop to 80fps for a second and jump back etc.Very abnormal behavior as I am playing the same games with the system with nvidea rtx 4060 without any of these issues!

Exact same issue with similar specs instead with a i5 13400 lots of stutter even with variable refresh rate.Tried everything I can think it could be seems like a arc b580 issue.

The fact that the same behavior occurs on a different system with higher specs reinforces this. I put forward to use IGCCs :frame rate limit: option instead of in-game VSync to see if frame pacing improves. Since your monitor doesn’t support VRR, VSync at 60Hz may exacerbate shader compilation hitches. Testing without it can help. 

Some titles (PUBG, RDR2, Witcher 3) allow you to pre-cache shaders to reduce in-game stutter.

To be clear, exactly, the Arc B580 is functioning correctly, but its current driver optimizations still lag behind NVIDIA’s maturity in certain titles. If you’re not seeing performance degradation outside of these micro-freezes, the card is still operating within spec.

Since the issue persisted across different systems, it does point strongly toward a driver-level limitation with the Arc B580. For now, sticking with your RTX 4060 makes sense, but I’d advise checking back with new Arc driver releases, as Intel has been rolling out fixes frequently with their new driver version here
