ok well, due to the failure of shattered horizon to play nice with my NVIDIA Control Panel Options (which i optimized for my OGRE 3D testing D:) i will:
be downloading garry's mod and whats required asap
getting the rnd svn manager
acquiring the addons for wirebuild
and building..... just i still dont know what yet xD
also thanks for the support.
well now my OS is on hold cause i can only do 1 thing at once (which at this point would be OGRE 3D). but im still waiting to be accepted as a NVIDIA Developer and have my Dev Account created so i can install the PhysX SDK, and in turn compile NxOGRE. Not sure where im going to go with OGRE but possibly since its PhysX we're talking about possibly a simple sandbox/simulator. both of those have interested me but i can only do 1 at a time so 1 will have to wait.
OGRE 3D has some damn awesome possibilities (even voxels for fully destructible objects). Still unsure whether it supports DirectX 10/11 fully.
As a side note (aside from you encouragement xD) tell me whether you want a REALLY realistic sandbox or a simulator. (mind you im still exploring OGRE ALOT, but i will get it done. eventually......)
