20160403 17:02:54 <rmk0> oops

20160403 17:03:18 <rmk0> sorry, i always manage to post the wrong URI
20160403 17:03:57 <rmk0> nice to finally have concrete numbers for how long each part of the pipeline is taking
20160403 17:33:23 <Eclesia> it's a good start
20160403 17:43:21 <rmk0> am currently on about the worst possible hardware that you could use for 3.3 support... intel hd something something
20160403 17:43:31 <rmk0> if i can make it run well on this, it'll run well on anything
20160403 17:46:35 <rmk0> the hardware is so capable that you get performance warnings if you use more than one color buffer
20160403 17:47:03 <rmk0> i hear it has a whole six threads for rendering shaders
20160403 17:49:42 <Eclesia> can that be compared with cude cores somehow ?
20160403 17:50:00 <Eclesia> cuda*
20160403 17:50:13 <rmk0> how d'you mean?
20160403 17:51:18 <Eclesia> you talk about 6 threads, but gpu used something a little different, 'process units'/ 'cuda cores' / 'programmable units'
20160403 17:51:41 <rmk0> oh, right
20160403 17:52:06 <rmk0> i think programmable units is probably the better term
20160403 17:52:18 <rmk0> obviously modern graphics cards have hundreds, if not thousands
20160403 17:52:20 <rmk0> this has six
20160403 17:53:11 <Eclesia> bahh that's okay, I only have ~300 times more that's all, no big deal
20160403 17:53:17 <rmk0> hehe
20160403 17:53:46 <rmk0> was susprised to learn that the gbuffer rendering was taking the longest
20160403 17:53:49 <rmk0> *surprised
20160403 17:53:55 <rmk0> expected lighting to be more expensive
20160403 17:54:02 <rmk0> both read and write heavy as opposed to just write
20160403 17:54:17 <rmk0> Eclesia: what g-buffer format are you using?
20160403 17:55:52 <Eclesia> surely one of the most expensive : http://pastebin.com/T7hdJcg4
20160403 17:56:11 <Eclesia> I didn't make any optimization
20160403 17:57:01 <rmk0> yow
20160403 17:57:07 <Eclesia> ^^
20160403 17:58:33 <rmk0> annoying that GL_RGB8 isn't a color-renderable format
20160403 17:59:03 <rmk0> especially given that some of the other rgb formats are
20160403 18:00:03 <Eclesia> well I stopped considering RGB as Red Green Blue. it's just first band, second band, third band.
20160403 18:00:32 <rmk0> yeah... a three-band 8-bit unsigned normalized format is what i'm after!
20160403 18:00:42 <rmk0> the spec doesn't guarantee the existence of any
20160403 18:02:33 <Eclesia> I have a train tomorrow morning (at 5H), so it's early but since I will have to get up in the middle of the night I'll try to get some sleep ...
20160403 18:02:37 <Eclesia> so good night +++
