CPU can't do stream processing it seems...
Ok, I just tested the "streaming" idea for the cpu. Streaming idea: "do many reads, do many writes, repeat". Non streaming idea: "do single read, do single write repeat". The non streaming idea works faster. (Streaming idea requires multiplications and some extra looping, not sure if that slows it down... 3 Oct 2009 15:29
OpenGL performance benchmarking ! ;)
Hi, I haven't tried this yet... but this kinda sounds good: http://www.spec.org/gwpg/gpc.static/whatis_vp8.html Could be used to detect what's fast and what's not ;) Bye, Skybuck ;) =D ... 3 Oct 2009 08:49
Other performance tips.
This document is nice: http://www.opengl.org/resources/code/samples/s2001/perfogl.pdf It mentions something interesting: "Depth testing is expensive..." I am not sure if this includes verteces going out of view or so... in 2d mode... Maybe depth testing is not required to make verteces go out of view b... 1 Oct 2009 07:15
GPGPU example plus needed OpenGL and CG libraries for Delphi 2007 now available ! (Benchmark results available)
Ok, I just updated the example... it now uses the vcl/form/canvas for the hdc. I also ran a little benchmark, problem size 16.000.000 iterations 200 Graphics card: GTX 7900. Some formats didn't work... especially the R program seemed to hang or be super slow... otherway, don't use those formats ;) Conc... 28 Sep 2009 02:40
