Bioshock Infinite Fix for PC (Steam, but works with other versions like EA, 2K, etc if you can find the defaultengine.ini file in the game directory)
If you are playing Bioshock Infinite, and you notice that the ground seems like it’s changing as you walk, or signs look almost unreadable regardless of how you play, it’s because your PC doesn’t know how to properly make use of your RAM, and Video RAM.
To Fix the Bioshock Infinite Texture Glitch Issue Blurry Signs:
Open DefaultEngine.ini in notepad.
It can be found in your Steam folder under Steam\steamapps\common\BioShock Infinite\XGame\Config
Edit to the following and save (use CTRL+F to search)
[TextureStreaming] UseTextureFileCache=False
TexturePoolSizeReductionMB=1500
PoolSize=3000
LowPCTexturePoolSizeMB=256
If you have a high end PC, that has NO problem running on Ultra (2080 or better) then:
UseTextureFileCache=False
TexturePoolSizeReductionMB=2000
PoolSize=4000
LowPCTexturePoolSizeMB=512
And if you have a low end PC, and need to try this trick (might not work unless you turn graphics preset to low or medium)
UseTextureFileCache=False
TexturePoolSizeReductionMB=1000
PoolSize=2000
LowPCTexturePoolSizeMB=256
