For newer computer setups running on Windows 10 versions 1809 and newer, you might notice that our current graphics card driver has DCHU attached to it as seen in the image below. This stands for Declarative, Componentized, Hardware Support Apps, Universal API compliance. This is essentially a new driver structure for hardware manufacturers.
The following is an official statement made by SOLIDWORKS:
So what does this mean for SOLIDWORKS?
After Fall 2018 Hardware Manufacturers will begin shipping new systems with the new Driver structure.
Systems older than 2018 (or systems shipped with legacy driver model) may continue to use the legacy driver model moving forward with no changes required.
Older hardware is able to use the DCHU driver version ONLY if a clean Windows installation occurs. The OS cannot use both versions interchangeably and whatever type was installed first, will be the driver type going forward.
- You cannot install a DCHU driver on a legacy driver system.
- You cannot install a legacy driver on a DCHU driver system.
There is no benefits in performance or features to either driver structure. Customers should use the same type that their systems come with and should not try to change it.
