OpenGL is broken on {{revision|7634}} and later. See {{issue|4703}}, added to {{issue|4635}}..

===Frame Buffer Effect===
=== OpenGL ===
OpenGL is broken on {{revision|7634}} and later. It was not fixed by the new OpenGL backend from the GLSL merger in {{revision|3.5-1064}}. See {{issue|4703}} and {{issue|4635}}.

=== Frame Buffer Effect ===

<!--Please remember when editing this section that it requires high resolution monitors to really see this effect-->
Referring to {{issue|4317}}, the game uses some sort of frame buffer effect that looks quite bad on high resolutions, creating pixelated ghosting and an annoying blurred look. The higher the resolution the more obvious the problem becomes. The effect is only present in DX9 and DX11 GPU back ends.
As part of it's sumi-e style, Ōkami uses some sort of frame buffer effect to add contrast and flatten the image. Unfortunately it doesn't scale with Scaled EFB and looks increasingly worse the higher the resolution becomes, creating pixelated ghosting and a blurred look. There is no known solution. See {{issue|4317}}.

*The only known workaround is to go back and forth between EFB to Ram and EFB to Texture or disable EFB Copies while the game is running. This will "stick" the effect, and allowed you to move around away from it. However the effect is still there, just frozen, so it has artifacts. Furthermore it is darker and lacks contrast: it is not how the game was meant to look.

'''''OpenGL for Okami is broken on {{revision|7634}}. Use {{revision|7633}} and older to perform this trick. See {{issue|4703}}'''''
 
The OpenGL back end does not render the effect, allowing an old EFB to Texture trick to become permanent and easy. It is less accurate, with some dimming and other problems, but it improves the visual clarity of the image considerably. To fix the effect's problem, make sure these settings are active '''before starting the game'''.
*OpenGL as GPU back end
*EFB Copies is on (not disabled)
*EFB Virtual is on
*EFB Ram is off (it's not used)

===Randomized Text Bug===
If the Texture Cache Accuracy is set to "Fast", this bug will appear. It randomizes the text characters, making it appear to be another language. The setting second from the right (normal) and safer settings all remove the error. This is fixed on version {{revision|3.0}} and later revisions, as Texture Cache Accuracy is now always on and the setting has been removed.

===Celestial Brush Freeze===
For the Celestial Brush to function "Skip EFB Access from CPU" cannot be checked.


Early in the game, the game requires using the rejuvenation brush skill to continue with the game, performed by holding B and then pressing A on areas to be rejuvenated. However, using this skill will cause Ōkami to freeze. Fortunately, after first pressing A+B to start the rejuvenation process, if one continues to hold B for 10-30 seconds (depending on your CPU), it will eventually unfreeze, and allows use of the brush as normal. While it is tedious, by repeating this one can paint the river and proceed with the game.  
=== Celestial Brush Freeze ===

Using the Celestial Brush's rejuvenation skill will cause the game to appear frozen; audio and video will both be stuck. If you continue to hold B for 5-30 seconds (depending on your system), it will unfreeze and the brush will work as normal.
