LOW frames are unstable and fluctuate greatly when playing PUBG with a B580 graphics card.

[Miss]

您好，我正在用我的 B580 显卡玩 PUBG，并注意到 LOW 帧率波动很大，有时会下降到 10-20 fps，这会导致游戏屏幕卡顿。
当角色看向城市或复杂的场景时，游戏的平均帧率会急剧下降，从 200 fps 以上下降到 100 fps 左右，同时，显卡的利用率和频率也会急剧下降。
在我购买后的两个月里，我尝试了不同版本的显卡驱动程序，在游戏内切换 DX 版本，以及 dx11/dx11e/dx12，都未能解决问题。
主板 BIOS 都是最新的，并且 Resizable BAR 已完全启用。
我从来没有遇到过NVIDIA 4060的这种问题，所以我觉得跟电脑的其他配置没关系，但是你们的驱动优化还是个问题，希望能反馈给技术部门尽快解决问题。
配置：
CPU： 13600KF
主板： 技嘉 B760M AORUS ELITE AX-P
内存： 32G 7200 频率
图形： B580
驱动程序版本： 32.0.101.6913
系统版本： Windows 11 专业版 24H2 26100.4652

Thank you for sharing your experience with the Intel® Arc™ B580 graphics card while playing PUBG.

We understand how frustrating fluctuating frame rates and stuttering can be, especially when you've already taken proactive steps to troubleshoot.

To help us investigate further and provide the most effective support, could you kindly provide the following additional details:

System & Game Configuration

• Was the game working fine before?
• Have you tried reinstalling the game?
• When did the issue start? is it after a driver update, software update, or hardware update?

Driver & Software Details

• Did you perform a clean driver installation using DDU before switching versions?
• Have you tried disabling background applications or overlays (e.g., Arc Control, Discord, MSI Afterburner)?

Performance Logs

• If possible, please run a CapFrameX capture for at least 2 minutes during gameplay in a complex scene. This will help us analyze frame pacing and GPU behavior.
• You can also run the Intel® System Support Utility and share the .txt report to help us review your system configuration.

We’ve seen similar reports where DirectX 12 offers more stable performance on Arc GPUs compared to DX11 or DX11e2. If you haven’t already, we recommend sticking with DX12 and ensuring the game is running in fullscreen mode with V-Sync disabled.

Once we receive your responses and logs, we’ll escalate the case to our graphics optimization team for deeper analysis.

Thank you again for your detailed feedback—it’s invaluable in helping us improve the Arc experience.

Best regards,

Hello and thank you for your reply:

System and game configuration
1. the game is running well, there are no missing or corrupted game files.
2. yes , tried the game from fresh install.
3.It has been there since I purchased the B580 and have tried many ways to fix it.
4. also the system has been installed from fresh and checked the system files and there are no scenarios of missing or corrupted files.

Driver and software details
1. yes, every driver installation uses DDU to completely clean the installation.
2. Yes, tried disabling unrelated background programs, no effect.

Performance Logs
I used CapFrameX to capture a copy of the multiplayer scene data, and a copy of the urban area viewed from a distance, but I found the software to be terrible at recording Low frame touchdowns in this regard, he would not produce a record. This is not as good as MSI Afterburner, which displays in real time the actual number of frames when a Low frame bottoms out and the screen causes a stutter.

Also PUBG is a game that has terrible support for DX12, the frame rate drops a lot compared to DX11 and DX11e, I have tried switching to DX12 but the performance doesn't get better.

[Miss]

Hi, I've been testing all afternoon today, and after switching the DX version to DX12 Low frames bottomed out and eased a lot, rarely reoccurring.

However, the overall frames were reduced by about 80-100 fps compared to DX11 and DX11E, and the frames in scenes from a distance looking towards the city didn't change much, only about 100 fps as before.

So I'm still hoping to optimize DX11 on the driver side to solve the problem of Low frames bottoming out under the DX11 version.

Hello Miss,

You’ve already done more than most users typically do, so kudos for the thoroughness. What you’re experiencing with PUBG's DX11 performance and frame dips might be driver-level or engine-level. 

I'd like to delve deeper and verify specifics like the graphics models, precise driver versions, and any system errors. Utilizing the Intel SSU tool will enable me to collect detailed information about your system setup, which could aid in identifying the underlying cause of this issue.

Best regards,

Hi, thanks again for your reply!

Here's the report I generated using SSU, hopefully it will help you guys in dealing with this issue, thanks.

[Earl_Intel]

Hello Miss,

Thank you for sharing your system’s SSU logs—we appreciate your effort in helping us better understand the situation.

Based on our initial review, the issue you’re experiencing with PUBG appears to be a known compatibility concern related to the Intel® Arc™ B580 graphics card.

No worries—I'll be conducting a deeper internal review of the logs and will provide you with an update as soon as I have more information.

We appreciate your patience and will do our best to get this resolved promptly.

Best regards,
