description:When i took the first try to load a skimish game using the default map and setting, the game load failed after a few seconds. But the problem won't reoccur when I restart the program and recreate the skirmish game. In the end, thank you so much, finally i started my first openRA2 game, It's exciting!

Interesting. I thought that only happens on Intel HD 3000.
That's not good :/

[phrohdoh]

Hey there, thanks for the detailed report!
@Penev is this the same issue you are having, or do you just not get rendered terrain?

[penev92]

This sounds like the one I'm getting.

[phrohdoh]

This is majorly unfortunate.
Seems RA2 does need some special time set aside for sheet optimizations.

[RoosterDragon]

OpenRA#9627 will buy you a good ~250 MB to play with - but yeah after that you need to majorly optimize those sheets somehow - they're huge and there's too many.

Alternatively OpenRA needs to cache stuff a bit less (like, say, sheets for tilesets we're not using right now) so there's less memory pressure at any given time.

@phrohdoh
when i succeed in restarting the game, however, the terrain is not rendered. i can see only grids, cross lines on the terrain but no grass or dirt.

[phrohdoh]

This is indeed the issue @Penev is running into.
The issue here is that RA2 uses a lot of texture space and we don't handle that properly as the other mods do not come close to the amount of art that RA2 has.
