HDMI Game Mode

[12characters]

I am curious about the new HDMI game mode option in the ini file:

Code: Select all

; Enable game mode on HDMI output. It may give you better optimization on some displays, but also 
; can give worse result on others. Default is 0 (non-game).
;hdmi_game_mode=1

How can one tell whether it improves the performance or not? Does it require that the display utilizes HDMI 2.1?

I think all it does is tell your TV to automatically activate “Game Mode” if it has one. If you already manually turn on your TV’s game mode, then this option is useless.

The DE-10 does not have HDMI 2.1 so i´m pretty sure that is a NO on that.
The other i have no idé at all about.

Based on some googling, I am guessing that the option refers to Auto Low Latency Mode (ALLM) which fits your description.

ALLM was introduced in the HDMI 2.1 specification why I presume that it will do nothing on older displays.

It appears to be a useless feature in most cases. But why would it give "worse result" on some displays?
