图形性能改进/ GDI替代？

Question

can anyone suggest any alternative to GDI? The reason is that I have data that updates rapidly and GDI doesn't support that kind of render velocity... I've tried SharpDX & SlimDX, but none seems to work properly (can't force them to draw on form without errors)

Update 1: I'm developing in C#

Update 2: Data is binded to Visual Studio 2010 default Charts control. A lot of code has been written to add functionality & lags were discovered after large amount of data incoming. Reason is that I need compatibility with .NET Framework 4 & Windows XP and higher. After spending a lot of time investigating, I've discovered that SlimDX and SharpDX have strict requirements to videocard, drivers, and problems running on Windows XP.

Answer 1

GDI is software only rendering, as well as GDI+ which handles alpha channel for transparency rendering. These two libraries are really limited and slow compared to a GPU based one.

My suggestion is that you should invest the time to implement a SharpDX Direct2D based drawing engine. I never heard about the issue you talked about with forms, I use SharpDX with Winforms and WPF and everything's going great!

If speed is the most important criteria, then you'll have to invest time into a GPU based rendering engine, GDI is way to slow and not adapted to real-time rendering.

老实说，我感到奇怪的是，GDI在这种情况下还不够，但是还有很多选择：您可以选择DirectDraw以获得完整功能，可以选择GDI +获得更高级的操作和选项，甚至可以选择外部软件，例如GTK +。
