[Scummvm-devel] Increasing maxHeapThreshold (for GF_NEW_COSTUMES)

[Joost Peters]

Hi,

The current default maxHeapThreshold value for games with the 
GF_NEW_COSTUMES feature set appears to be too small to contain all 
resources for certain scenes in V7/V8 SCUMM games, causing unnecessary 
reloading from disk.
This is especially noticable in the town in COMI when hovering the mouse 
over the exit(s) it'll re-load the mouse cursor every time, which causes 
some serious slowdown.

Which is why I want to increase the default size of this buffer from 
2.5M to ~6M (as the PS2 port already does via an #ifdef).
My only concern is that this might push certain ports (most notably the 
Dreamcast port) over the edge as far as memory requirements are 
concerned for games with this feature set, which is why I'm bringing it 
up on the list.

The increased memory usage shouldn't affect the vast majority of our 
supported platforms, and ofcourse ports to devices with little memory 
can always decrease the size by basically doing the opposite of what the 
PS2 port does now.

Any feedback or objections to me making this change?


Regards,
Joost
