Hi,

 

My video card has 4gb of dedicated memory but when I query the DXGI adapter description for DedicatedVideoMemory property, it return me a negative value of -1073741824.

 

How can I get my real video memory ? Look like it's bugging with large memory video card.

 

Thank for your help.

Yes you are right, if I compil my application with a 64 bit target, I got the correct 4Gb value from the DXGI Adapter Description.

 

That throw me another problem... I need to store that value into a Int64, cause the Int32 throw me an overflow exception.. Now I need to think how to manage 32 bit system correctly, because compiling my application on 64 bits target will not allow a 32 bit system to run it..

 

I am a "traditionnal" application developper, I am doing SharpDX engine just for fun so that kind of 32/64 bit problems are new to me ;)
