De allocating vram

[JayCee6828]

I have a Radeon HD3600 graphics card and recently installed X-Plane 10. At the same time I allocated some VRAM from my system memory but now want to take that back as it is slowing down the game.

 

Can you tell me how I can find out how much memory is allocated to VRAM and then how to de allocate it.

Hi

At the same time I allocated some VRAM from my system

I assume that you did this through the BIOS > Advanced Chipset Features ( or similar ) ?

If you enabled it there you should be able to disable it there too.

Thanks for the reply.

 

I am not sure now how I allocated it, I have a vague memory that the installation program asked me to let it allocate some and I accepted that but I could be wrong.

 

I have looked at the chipset settings and the share memory item is set to auto - should I change this, it gives a choice of various values?

 

I am asking this as an answer on the X-Plane 10 forum told me that using extra vram than that on your graphics card (512Mb) will slow the program down.

Hi again

 

should I change this, it gives a choice of various values?

Try disabling it - run the game.

Set it to the highest value - compare the running of the game now.

 

You can always go back and change the settings :)

 

How much physical RAM do you have ?

Hi Ken,

 

Thanks for the reply.

 

I can't disable it in the chipset settings it only gives choices of auto or various amounts of memory, not including 0

 

I have 4Gb of memory in the computer

In that case try the max and min settings to see if there is any difference.

 

The reason I asked how much RAM you have is that VRAM utilises this and if the setting for VRAM was too high it may have a detrimental effect on the rest of the system.
