Nice, this is exactly the kind of thing I had imagined when I wrote that comment :)

Looks like it deserves some testing and, if I'm understanding this right, it should be done for the other triangle primitive types as well (triangle list, fan, plus all the non-indexed types). Could also fall back to flushing the cull mode if those are encountered...

@hrydgard hrydgard added this to the v1.7.0 milestone Apr 27, 2018

I haven't find a game to test other primitive types, so all those fallback to flush.

Just a note: this in theory should fix #1319 and #6958, I think. Possibly also #10597.

GTA use triangle fan, need handle it.

if (numInds <= 0) return;
indexOffset = index_ - indexOffset;
int numTris = numInds - 2;
u16 *outInds = inds_;
const int v1 = clockwise ? 1 : 2;
const int v2 = clockwise ? 2 : 1;

Tomb Raider use GE_CMD_TEXOFFSETU and GE_CMD_TEXOFFSETV frequently, but not quite useful.:grimacing:

I think it's some engine, there's other games that do that too (basically the whole point of the gstate_c.uv optimization.) Makes sense to add them here.

Looks good to me - I think we should merge.

dc.cullMode != -1 && gstate.isCullEnabled() && gstate.getCullMode() != dc.cullMode could possibly be factored into a method, but I think it's a good change either way.

WOW 😃 Naruto Ultimate Ninja Impact 1 now running smooth in 30/30 FPS unlike in previous version this game is running very slow but now it's fast maybe because of this "handle cull mode of indices"?
