Lowering Your Video Settings

One of the most common reasons players get the Failed To Lock Vertex Buffer In Cmeshdx8 Lockvertexbuffer error is their gaming rig being too weak to run CS2 (CSGO) properly.

Update Your Graphics Card Driver

Your graphics card is a crucial hardware component to how well your setup can run Counter Strike 2, as playing CS2 (CSGO) without a graphics card is not ideal. To ensure you are playing CS2 (CSGO) on maximum performance capability, you must keep your graphics card drivers up to date.
