+#### **NOTE**: Update Nvidia Drivers
+- A recent glslang change exposed a bug in the texel fetch behavior on Nvidia devices under certain situations.
+- Previously, we reverted the glslang change which exposed it.
+- Nvidia has since resolved the issue, and we are now removing the workaround.
+- Driver installs with the fix are available on their download page, just look for:
+ - Linux Drivers starting with version 367.35
+ - Windows Drivers starting at version 372.54
