Disable 3d Rendering.

[fusspawn]

Hi,

Lets prefix by saying my dev/wow/only pc is crap, its a netbook for crying out loud.

So in the process of trying to speed up wow so i can actually use this machine for anything while botting and hell perhaps even get a second client running and botting to.

Ive been trying to disable the 3d rendering side of wow, (It would be nice to keep the gui rendered so i can at least check the bots not being totally retarded.)

My first mission was detouring the D3d render methods, mainly DrawIndexedPrimitives,

After i got that working i set about trying to find a way to see if what was being draw was the gui layer, or a 3d based one.

Ive tried various methods,

VertexCount % 2 == 0; (All Gui items are rendered as squares). alas lots of 3d items have a nice even vertex count. so that idea what out.

I then hoped that wow was just using Textured Quads scaled to what ever size they need for that specific item. Alas no go, Some of the gui layer has more than the 2 triangles that make up a quad.

Wow also batches up Gui Rendering so PrimCount/Num vertex would never work,

Im running out of ideas,

Note: I can completly disable rendering just fine, But i really want to keep the Gui on screen :/

Any DirectX Gurus have any suggestions as im at a loose end.

I think you're going to be hard-pressed doing what you're trying to do from the DirectX layer (it may not even be possible tbh).

Have you thought about just using an engine hook? It would probably be a lot easier...

[fusspawn]

Hadnt thought about that way tbh, Ive seen it done inside of other games ISXEve had it as an option. Guess ill go look at Some of the engine code then . Thanks for the hint.

Shouldn't it be possible to just render things when an orthogonal matrix is set?
That should be mainly the ui.

[fusspawn]

Ill take a look into that, Still mostly new to me so yeah things are going slowly.

Check out viewport. I'm pretty sure most of world is rendered with

viewport.MinZ = 0;
viewport.MaxZ = 0.94f;

Oh the Irony, Your helping with suggestions. Its your codebase im implimenting it in

[mcpickle]

If i should fix/Improve this to 3.5.5a would you have any issues with it being posted?

Are you still thinking about posting your updates?

Hello!
Tell me please, how you disable 3d render?

[Empted]

Actually I'm tired of PM messages after some incident on this forum. To disable world rendering just make this [9B3F70 CGWorldFrame::Render] function do nothing (it take no params so retn at start will do). To enable do reverse, to disable all rendering do nearly same thing with another function you can easily find in the dump thread..

You don't need to hook something! Minimize WoW will draw down CPU usage.

[Empted]

Be carefull, CGWorldFrame::Render is now scanned by warden (Offset: 0x5EFE10 Length: 9 Bytes: 55 8B EC 83 EC 40 0F 57 C0), so skip some bytes before writing your opcodes and don't debug with software BP.

You can use VEH hook.

[Bananenbrot]

You can use VEH hook.

If he wants to get banned, then yes...

[ValvePro]

Why that warden doesn't detect VEH till now.. sure you shouldn't use PAGE_NOACCESS! instead of this u have to use PAGE_READONLY.
