Does anyone know if there's a version of CWSDPMI that can use more than 64 MB of RAM? Dosbox-Rendition forces 512 MB of system RAM, but the vQuake only allocates 60 MB for some reason.

Hi sharangad,
I found some resources on CWSDPMI memory allocation over 64MB:

Oh wow! Thanks! I need to look into this for vQuake.

How do you determine the version of CWSDPMI? I think you need 2.0 or later for this to work.

In DOSBox-X the command to check version is cwsdpmi -p

vQuake appears to ship with 0.9. I did try looking for alternate binary versions of it without success.

[EDIT] Nm, found version 7.

That seems to use over 500 MB, but for some reason RReady doesn't render correctly.

[EDIT] It does render properly after restarting vQuake, but it still won't run at 1280x1024, something about a v_alloc error. I think this relates to GPU memory. 12x10 needs ~5 MB for double buffering. I don't think v_alloc actually does anything on the GPU, the VRAM is managed through the Verite libraries embedded into the game. Also version 7 produces a swap file error, but the game still runs.
