AGS: Old Skies (Steam Demo) significantly slower intro sequence compared to original game win build

win11, sdl/opengl - no matter

What is the "intro sequence"? You mean the wadjet eye logo animation?
Are you using a daily build or the 2.9.0 release? Daily builds may be slower as not all optimizations are enabled

Replying to tag2015:

yes wadjet eye logo animation, and yes win64 daily build used

PS. 2.9.0 x64 plays logo a bit faster but still visually slower than native

The general issue is that the upstream AGS engine has hardware acceleration, and ScummVM does not. We have CPU optimizations but that's not the same thing. This is noticeable in games using high resolutions or advanced graphical effects, and Old Skies is a 1920x1080 native game.

I am a betatester for this game and using the latest beta I can't see a significant slowdown, but it may be different on other systems/GPUs.
I made two screencaps (note that I cut the loading screen in the Steam capture)

You can also try disabling VSync. It may cause screen tearing but you'll certainly gain some FPS.

Well, I'm closing this one, because it's not really a "bug".
I played the game personally on Windows and there are no significant slowdowns (only in some scrolling scenes, but not as much as to affect video/audio sync). We also got reports that the game runs well on Mac.
