I am making a game with the Allegro 5 game library for C++ and I am using visual studio 2022. When I run my game these messages are in the output. The messages keep appearing very fast so I think there might be a slight performance loss.

Here are the strange messages:

Strange messages

I was making a simple game with the Allegro 5 library. Upon noticing these strange messages, I tried googling them but came to no answer.

https://community.intel.com/t5/Developing-Games-on-Intel/igdumdim64-dll-is-spamming-Windows-log-via-OutputDebugString/m-p/1422306

As per this link, the problem occurs because of the UTF-16 string "Peiran message result is: %x" which is present in system files igdumdim32.dll and igdumdim64.dll.

The problem also appears when running outside Visual Studio, viewed using DebugView (by SysInternals).

igdumdim64.dll is loaded when the program is run. It appears somebody left a debug message on the dlls and it's getting called between 2 and 16 times per second.

The issue seems to be in Intel Ultra HD Graphics Driver. The suggested solution in the link is to update the driver and check again.
