Emulator

it's probably cause of the implementation of depth textures in 4599 cause your graphics
card might not support them

What Plugin do you use ? OpenGL or D3D.
If you use D3D they introduce the choice between EFB to Ram (buggy and slow)or EFB to
Texture : Try with EFB to Texture.

A few additions to this entry that will help:

1. I transposed the numbers above - it should read R4620 instead of what I have.
2. I am using the DX9 plugin with an ATI Mobility Radeon 4670.
3. I have confirmed that this bug did NOT exist with R4613 so it could not have been
   the revision you speak of that caused this issue.

I don't see any option for EFB to Texture with D3D, as I do with OpenGL - are you
sure you don't mean OpenGL?

this option is also in the DX9 it was added by luisr14 in r4620 to the DX9 did you take
the DX9 from an older version if you did then it won't show these options

Thanks for the help. Ok, just grabbed R4628 and now I see the option. However, it
does nothing. I tried "Copy EFB to RAM", "Copy EFB to Texture" and just turning
the "Copy EFB" option off entirely. Same issue.

Also - since a recent revision, OpenGL has been crashing entirely (no matter what
game you use) so I can't switch to that plugin to test this. In fact, that may need
to be another issue submitted if it isn't already.

Anyway, try Metroid Prime yourself and you'll see what I mean..

i can't cause my graphics card fails miserably with depth textures so i just copy over
old DX9 but when i did try it with new DX9 i noticed that the speed was terrible in
Prime with EFB on i was a 2FPS at my ship but when i turned it of it instantly went to
30FPS but the top half of the screen was grey with it on or off making any sort of
attempt at playing the game nearly impossible

so i gotta wait till roodolfo fixes it

It's fixed in the newest rev
