# Description: In hardware mode, fog effects in snowstorm or poison gas areas are not displayed properly and cause the emulation speed to drop drastically.
Software mode runs normally, but is slower than hardware mode everywhere else in game on my computer.

The map shows how to get from the attached save to the area with the slowdown.

Can you make a GS Dump(hold CTRL + SHIFT + F8 for 1 to 2 seconds)of the area with the broken fog effect?

Still present on latest git. Possibly due to unsupported clamp mode (see below) - will do testing outside of GS dump later.
