Twilight Princess GCN Performance

[Heyjew]

Hey guys,
This is my first post but I've been using Dolphin for a while and I want to say thanks for continuing to develop an awesome program. Anyway, I'm having issues running Twilight Princess on even the lowest settings. My computer specs are as follows:

Operating System: windows 7 x64
Processor/CPU: i5 3570
Video Card/GPU: AMD Radeon R9 280
Memory/RAM: 8GB Kingston
Dolphin Revision Currently Using: 4.0-3954 x64

I can run SMG2 on 1920x1200, 16x filtering, etc at a constant 60fps. My question is mostly, whether the ISO I use has any major impact on performance or not, because I ran this game just fine on my older video card (GTX460) with a different ISO even while streaming on Twitch. Thanks for the help in advance.

For this particular game, my NVIDIA is much, much better because it's faster on OpenGL, and this game is one of the games that absolutely need Buffer Storage and the benefits it brings. Radeons aren't quite as fast in that situation, and this game being the absolute extreme, suffers.

So there's not much I can do?

Are you using the Twilight Princess patch?

Anisotropic Filtering doesn´t affect performance at all. Make sure you have HLE selected. If that still doesn´t work, try using the ZTP hack in the Patches section (right-click ZTP/Properties/Patches tab).

If you have it set to efb to RAM, make sure that the enable cache box is ticked and set the slider all the way to the right.

Enabled the patch today and it's smooth. Thanks.
