I'm writing to enquire about WPF and Hardware Acceleration. We're developing an application with WPF and we have problems with performance and with ComboBox deployment behind the form. If we deactivate hardware acceleration we have a normal behavior. But if we activate it our performance decrease dramatically, doing the application unusable. Our environment: Core 2 Quad, Q9550 2.83Ghz 3GB Windows XP Pro 32bits Ati Radeon HD 3470 512 MB with last Catalyst version, Driver 8.931.0.0 Date 05.04.2012

 

We're developing a desktop application, 3.5 Framework,  WPF with a distributed DB SQL Server 2005. We're using MVVM as presentation pattern.

Our windows are created with "AllowTrasparency=True" but with older drivers we haven't combobox issue. Our customer need to update drivers because they need use projectors. 

 

Why does this happen? What consequences would hold off graphics acceleration?
