Well there is newly created Rendition Heritage cards with 16mb on board.

RReady creates an opengl context using the window handle passed into rredline.

It's the same window and it works because the window hasn't been made directx compatible.

Actual rredline has no issue with the surface being directx compatible, but rready does. In fact that's why games like interstate 76, myth tfl and MechWarrior 2 series need dxwnd or some other directdraw wrapper. Thats also why MW2 can't switch from opengl to directx and vv.

Windows only allows a surface to be directx or opengl compatible. A similar restriction exists for vulkan, a whole new type of surface incompatibility.

well in any case Re: RReady (Rendition Verite wrapper) Test Build (Alpha 1)
just want you to notice it, and not miss.

Do games actually run faster on it?

idk, i don't own that type of card, if someone at forum could answer, but unfortunately not me at the moment.

The message loop for the window lies in the game itself.

Vhexen2 needed to intercept a bunch of messages when using upscaled resolutions. It did that by replacing the wndprocOrig (using setwindowlong gwl_wndproc) and intercepting a few messages. The rest it passed through to the original wnndproc.

This is because vhexen2 centers the window but had no idea that the resolution is higher than default. So it ends up with a screen fourth quadrant window with the other 3 quadrants of the window offscreen.

I'll double check. What I'm saying is that textures can't be loaded beyond 8mb because they can't be accessed as textures. Needs one more bit to goto 16.

i think it may perform faster, coz 63 mhz core clock and vs 55 mhz fastest Rendition Verite old card which one among them is Herculess Thriller 3D

Well rready works, so it must be possible. I can knock up a test app using rredline to check. The api supports it but I'm not sure that physical hardware can.

if someone respond here Rendition Verite Thread

Oh and creating a context onto an existing window works because opengl doesn't need to render during wm_paint.

ICR 2 appears to be carrying out FIFO writes to VRAM.

DMATest writes out crazy FIFO values. The command Ids go from 0x00000000, 0x11111111, 0x22222222, ..., 0xEEEEEEEE.

I think the custom firmware comes into play here, because the FIFO commands are garbage. I just hope the games don't rely excessively on custom firmware, OR I'll have to add a command processor to the shaders.

There's yet another Int 10h call in Whiplash. This time it's function 0x1584. I wonder how many of these there are.

I think that's to exit 3D mode.

Was the resolution correct on exit?

Also, 16 MB Verite boards are possible. The memory buffers are chained, so you could have multiple buffers for filling up 16 MB.

yes all good, resolution correct.

Whiplash briefly flashes an error message (Invalid instruction) before returning to DOS.

Lol what? nascar need mouse which already present in dosbox. Well you can try use cute mouse exe driver, i use it from freedos project, maybe its do a trick?
