英特尔Ultra 5 338H Arc核显不兼容CATIA v5 R28

cocojee — Sun, 10 May 2026 07:29:24 GMT

我购买了型号为Honor Magicbook pro14 2026笔记本，搭载处理器型号为Ultra 5 338H，显卡型号：英特尔Arc核显，核显驱动版本32.0.101.8509，安装CATIA版本为CATIA V5 2018。

我目前碰到的问题：使用CATIA查看或者编辑三维数模时异常卡顿，性能甚至远低于我2022年购买的笔记本，那台笔记本处理器型号为AMD的6800U，6800u核显性能参数是不如这个338H的，但是那台笔记本就很流畅运行CATIA。

目前，我没有办法为自己或同学解决这个问题，我真的很沮丧。当前的兼容性问题未来会越来越多地困扰更多的设计人员。

我的请求是尽快协助我，告诉我该如何调整或者贵司尽快出具兼容性的驱动。

Hi cocojee,
Thank you for posting in our Community. I understand when performance does not meet expectations, especially when comparing it to other systems that appear to handle the same workload more smoothly. To better assist you and identify the root cause more accurately, I would like to ask a few questions:

Could you confirm whether CATIA V5 is fully updated to the latest available service pack or patch version (e.g., V5-6R2018 SP updates)?
Does the lag occur in all CATIA functions, or is it specific to certain operations such as 3D navigation, rendering, or editing?
Have you tested CATIA performance after updating the Intel Arc graphics driver beyond version 32.0.101.8737 (if available)?
Is hardware acceleration enabled within CATIA settings, and have you tried toggling it to compare performance?
Are there any background applications running during CATIA usage that may be consuming CPU or GPU resources?
Have you tested the same CATIA workload on different power modes (e.g., performance mode vs balanced mode)?

Your request regarding compatibility and driver optimization is well noted. At this stage, performance differences can often be influenced by software configuration, driver maturity, application version compatibility, or OEM-specific system tuning.

Have a nice day!

您好，

1、CATIA已经是R28最新版本

2、我也试着安装了R2021、R2022都是这种情况

3、显卡驱动尝试安装过OEM提供的，也尝试安装了INTEL官网最新的，都没有解决

4、CATIA R28没有找到硬件加速的开关，相同的安装方式在另一台6800U（AMD处理器）上就能直接使用，那一台并不卡顿

5、在使用CATIA时，后台没有其他占用高的应用（通过资源管理器可以看到GPU占用一直在10%以内）

6、电源模式我默认开启的性能模式

Hi cocojee,

I’ll need to conduct additional research on this issue and will post an update in this thread once I have more information about this matter.

Have a nice day!
