/advshading 0 fixes the slowdown, but makes the game fugly obviously. |
|
|
further investigation showed this may be a driver issue. |

[quote][17:41:03] <baczek2> btw how come i've got 90 fps with /advshading 0 and 10 with /advshading 1? [17:41:12] <baczek2> when building stuff [17:42:09] <jk`gentoo@IRC> press [b] and check shadow/relect time usage [17:42:19] <baczek2> it's all drawworld [17:42:28] <baczek2> check that video [17:42:32] <jk`gentoo@IRC> strange [17:43:36] <baczek2> oh no wait [17:43:52] <baczek2> shadows/reflect are there too [17:43:56] <baczek2> but drawworld is more [17:44:07] <jk`gentoo@IRC> how much is ti [17:44:13] <baczek2> depends [17:44:49] <baczek2> no constructions on screen - about draw world is about twice as big as shadows [17:45:06] <jk`gentoo@IRC> ohh could be that zerver also added advshading to units in build [17:45:27] <baczek2> with a single nanoframe in filling with texture phase, it's about 4 times larger [17:45:38] <jk`gentoo@IRC> he did some mistakes in that code ?¼_?¼ [17:46:48] <jk`gentoo@IRC> it just isn't possible to do such stuff with the current unit renderer [17:47:00] <baczek2> fix plz ^^ [17:47:31] <jk`gentoo@IRC> i got lazy to fix other's bug[/quote] |

the slowdown also happens in 79.1.2. |
|
|
I added adv shading to transparent units only (or at least that was the intention). This was to fix bugs with rendering of submerged transparent stuff. Will check it out though. |
|
|
It's not happening with my 8800GTX, likely to be a driver issue. |
|
|
more info: doing this modification to the unit drawer (DrawUnitBeingBuilt) results in no slowdown: glDisable(GL_CLIP_PLANE0); if (unit->buildProgress > 0.66f) { const double plane0[4] = {0, -1, 0 , start + height * (unit->buildProgress * 3 - 2)}; /* glClipPlane(GL_CLIP_PLANE0, plane0); glPolygonOffset(1.0f, 1.0f); glEnable(GL_POLYGON_OFFSET_FILL); */ DrawUnitModel(unit); /* glDisable(GL_POLYGON_OFFSET_FILL); */ } /* glDisable(GL_CLIP_PLANE0); */ clearly, there seems to be an issue with clip planes in the driver. |
|
|
also, it doesn't happen when i comment out //unitDrawer->UnitDrawingTexturesOn(unit->model); |
|
|
yet more info: commenting out this in UnitDrawingTexturesOn //glEnable(GL_VERTEX_PROGRAM_ARB); //glEnable(GL_FRAGMENT_PROGRAM_ARB); results in no slowdown. |
|
|
also, enabling only the vertex program causes the slowdown. where is the one used here stored? |
|
|
Note that one of the earlier atiHacks also specifically disabled clip planes in DrawUnitBeingBuilt. |
|
|
status should really be 'worked around' - clip planes are disabled on atis now. |
