Slow 3D rendering in Acrobat Reader DC
Hi,
I've created a PDF doc with a 3D annotation. When I open it in Acrobat Reader (v. 18.009.20044), 3D rendering performance is very poor. The Preferred Renderer is DirectX 9 in the Preferences but, in fact, I don't see any differences between Software and DirectX 9: rendering is very slow in both cases. BTW, I have only two options: DirectX 9 and Software, no OpenGL.
On the other hand, when I open the same file in Acrobat Pro DC, 3D rendering is much faster with the DirectX 9 renderer. When I select Software renderer in Acrobat Pro, the performance is the same as hardware or software rendering performance in Acrobat Reader (slow).
I've tested it on several PCs with different NVidia graphics cards (GeForce GTX 960, GeForce GTX 970, Quadro M2000M with the latest drivers, Windows 10) and got exactly the same result: Acrobat Pro is fast, Acrobat Reader is slow with respect to 3d rendering.
Is it because Acrobat Reader does not support hardware acceleration?
If it does, how can I enable it? Do I have to do something else in addition to selecting DirectX in the preferences?
Thanks,
Roman
