TotalVidMem() on Windows 10.

Blitz3D Forums/Blitz3D Programming/TotalVidMem() on Windows 10.

DrawText ("Total RAM : " + TotalVidMem(), 30, 60)


returns an odd number.



My PC. 4 G Ram.
1 G Graphics Card.

Any suggestions ?

How else can know how much memory the application concerned if this command does not work properly?

The same problem:

My function to display unsigned integers is near the bottom:

DrawText ("Total RAM : " + unsigned$(TotalVidMem()), 30, 60)

This is how I use this feature?

As I convert this data in megabytes?

This was answered higher up in the same thread. Here is an example.

big = 2500 * 1024 * 1024  ; 2500 megasomethings

Print
Print big
Print unsigned( big )
Print VideoMB( big )

WaitKey

Function VideoMB( VidMem )  ; approximate number of megabytes.

	VidMem = VidMem / 2^20
	If VidMem < 0 Then VidMem = VidMem + 2^12  ; 2^12 = 2^32 / 2^20
	Return VidMem

End Function

big = TotalVidMem() * 1024 * 1024  ; 2500 megasomethings

Print
Print big
Print unsigned( big )
Print VideoMB( big )

WaitKey

Function VideoMB( VidMem )  ; approximate number of megabytes.
	
	VidMem = VidMem / 2^20
	If VidMem < 0 Then VidMem = VidMem + 2^12  ; 2^12 = 2^32 / 2^20
	Return VidMem
	
End Function

Function unsigned%( n )
	If n >= 0 Then Return n
	Local digit, prefix
	digit =  ( 10 + (6 + n) Mod 10 ) Mod 10
	prefix = 429496729 + n / 10 - ( digit > 6 )
	Return ( prefix ) + ( digit )
End Function


Return:


I'm a little confused, I have a video card of 1024 megawatts, 1 gig, e sto is what returns.

The question is, where the value of the memory of 4 GB of system memory or graphics card is taken?

I greatly appreciate the help and patience, I am ignorant of many things.

This is embarrassing , now I find that my graphics card is 2 gigabytes.

:)




Thanks a lot for the help. :)

My GFX is only 3GB, so you're not that far behind the low end.

I only have 1GB, and it still plays everything I want to..

Mine's not too bad either, seems to be handling what I need it to; but I know there's much more powerful stuff out there for the more finacially stable user.
