Game, "failed to lock vertex" and "internal driver error"

maxclark

hello everyone!

so i have been having some problems with my steam games, where I'll start the game and then after a while the game will close with a variation of messages ranging from:

"failed to lock vertex buffer in CMeshDX8::LockVertexBuffer"
and
"Internal driver error in IDirect3DDevice9::Present()"

the game would shut down at that point and yeah...


So i did some reading about this problem and read that it has something to do about my Kernel Memory (i dunno what this is and if someone could explain that would be great)(seen in attached pic) and this is divided up into Paged Physical and Paged Virtual...and what i read was that when this crosses the 150,000 mark then the game would close down...

so i got a software which monitored this and sure enough whenever the game would shut down, giving me one of those messages above, the Paged Physical or Paged Virtual memory would go above 150,000

so if anyone knows about this paged and virtual stuff that would be great for explaining to me what it is, and more importantly tell me how to control it and make sure it doesn't cross 150,000 when i play my games...

thanks to whoever can help me out...

First get memtest and run it to make sure you don't have a physical problem with your ram.

As for what that all means is basically you have so much ram. When windows requires more working memory then you have RAM it turns hard drive space into virtual RAM, which is called a pagefile. So where the process fails is if the page file gets corrupted it causes problems in the same manner that having bad RAM does. Windows trys to right or retrieve data from a corrupted part of the pagefile and it cacks.

This is the quick way to make sure it's cleared out, but note this will increase your boot times. However once you keep this setting on for awhile you can turn it off and go back to normal and hopefully the problem is fixed.

• Click Start
• Click Control Panel
• Click Administrative Tools
• Click Local Security Policy
• Click the "+" next to Local Policies
• Click Security Options
• Doubleclick "Shutdown: Clear Virtual Memory Pagefile"
• Select the "Enabled" radio button
• Click OK

Then there is a more direct approach to delete and totally recreate the pagefile. But usually that's not needed.
