Some new ge2.ini tweaks for 2GB systems
(as always: make a backup for this file, before you change something)

;optimize memory usage (all systems):
;use these cache settings (25% more):

Cache.SizeImage=160000000
Cache.SizeMaterial=80000000
Cache.SizeMesh=87500000
Cache.SizeSound=100000000
Cache.SizeCollisionMesh=50000000
Cache.SizeAnimation=50000000
Cache.SizeSpeedTree=12500000


; the maximum settings for 2GB Systems (ResourceCache on Medium)
; settings tweaked towards high

ResourceCache.u32ImageMaxMemUsage_Medium=96000000
ResourceCache.u32MeshMaxMemUsage_Medium=60000000
ResourceCache.u32SoundMaxMemUsage_Medium=20000000
ResourceCache.u32MaterialMaxMemUsage_Medium=21000
ResourceCache.u32CollisionMeshMaxMemUsage_Medium=1 7000000
ResourceCache.u32AnimationMaxMemUsage_Medium=35000 000
ResourceCache.u32SpeedTreeMaxMemUsage_Medium=80000 0

ResourceCache.u32ImageMaxMemUsage_TextureQualityHi gh=0

EDIT: optimized
Play on Resource Cache and Texture Detail <Medium>

These settings minimize the "smartheap-out of memory error",
the performance should be better than on un-tweaked <medium> settings.
