The original portraits in the game have 8 mipmaps,You would think making a new one would be the same.
Is there a way to export all the portraits at the same time,instead of one at a time?
Try saving it with two mips.
If the buttons only show from far away,then the game is adding default mips to the uniforms.That is why as you get closer it then uses the correct texture.
This is what fixed mine.I have a GTX460.
I turned off MSAA ingame.
I created an MLB2K11 profile in the Nvidia Control Panel
Anti-aliasing mode = Override
Anti-aliasing Setting = 8xQ
Maximum Pre-rendered frames = 1
power management mode = prefer maximum performance
texture filtering - negative LOD bias = clamp
with these settings I no longer have stutter or black screen dropping to the pause menu.
Being that you could not reproduce the error,I figured it must be on my end.
So I deleted my bookmark for the site and created a new one.I no longer have the error.
Thank you for taking the time to look into it.
