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.

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.

1V:\QUAKE>cwsdpmi -p

[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.

Does anyone know if the heap size can be increased in vquake?

I've seen the -heapsize command being bandied around, but it doesn't seem to work with the DOS version.

Thanks dude!

Streamed SODA Offroad Racing . Works well.
The game can crash after changing a lot of setting like Desert, Tropical, Country always cycle it. Takes a while.
After several demo runs 3 pairs or 3 demos. game crash.
This is game problem i think not a wrapper.

Other suggestions:

Make option if possible to force turn off mipmapping , this is heavily used in game, without it i guess game will be much sharp. and have crisp textures all the time.

Mipmapping is done internally in the game. This game's texture addressing is a lot like Speedy3D's with direct addresses used for everything. So I have no control over it. You might be able to hack it yourself to do that. The function to select a texture is VL_SetSrcBase, which uses an address instead of a texture like in VL_InstallTextureMap. I would do it myself, but I'm a bit bogged down.

OK got you, canceling) not trivial, ok

No no. It's not hard. It uses vl_srcbase to select textures VL_MemWrite to load textures. If you disassemble it, the mip mapping levels can be found and fixed. It just never occurred to me do that and right now I have no time. It uses the low level side of the RRedline api for texturing almost exclusively. Monster truck madness, vquake2, formula 1 and sub culture exclusively use the high level api. Everything else uses a mixture. [EDIT]Speedy3D is entirely low level.[/EDIT]

Oh wth! I'll take a look. But not this week,

What's more important pushing out the vQuake fixes or CGL? I think pushing out the fixes is fairly important, because otherwise I'll end up with too many things to test in one go.

I think CGL, I am just streamin and testing games, vQuake can be later for sure.
More priority on popular game Icr2 and exclusives like soda and rebel Moon.
Everything seems work and matter of time to fix.
It's maybe how I see it.
From time to time I will report every rredline or speedy3d games here about bugs, suggestions etc.

Soda fixing mipmaps is not RReady side it's game side, don't bother on it.

That's a bit unfortunate for me. I spent most of the day validating all the DOS apps today. I would rather get on with CGL, QEMU and all the rest.

i don't have currently all the dos apps and windows. And when i can gather all them together, so i guess i can do all the test?

With the store release? I should be able to finish the store (and certified alpha) release tomorrow and push it out, so yeah you should be able to, barring unforseen circumstances.

i mean if i can test all apps before push to store, instead of you, to preserve your time for other things?)

That would be much much better, yes (sheepish) 😀

ICR2 More Rendition Ready tracks:

Richmond needs a MIP map reduced version which is linked to in the video details.

These appear to work fairly well as well. Hopefully I'll access to an AMD GPU powered laptop soon, so some AMD testing with this game can be done. AMD GPU are hard to come by here.
