far cry a HDR

chcel by som vediet ako sa vtejto hre zappina hdr a ci to pojde na mojej karte x800gto
presne tak, ati radeon X800 nepodporuje SM 3, preto ma aj nizky vykon v 3DMark 06 ...SurrendeR napísal:Na ATi X800 nieje SM3 teda ani HDR nepojde...
treba dat vsetky postupne ..lubo188 napísal:chcem sa este spytat ci treba davat postupne vsetky patche alebo stati dat ten najnovsi patch
ATI have supported various HDR methods since the introduction of R300 with its floating point texturing capabilities, however NVIDIA have supported a more optimal method of High Dynamic Range blending, something that ATI's part have not been able to previously. With the entire range of chips using the R520 architecture ATI will now support HDR blending, but will do so under a number of formats:
* FP16 - 64-bit floating point
* Int16 - 64-bit integer
* Int10 - 32-bit 10-10-10-2
* Custom formats (eg Int10+L16)
The 64-bit formats will provide the highest quality, but come with the highest bandwidth and memory footprint costs seeing as each pixel is twice the size of a singe 32-bit pixel. The Int10 mode provides a level of Higher Dynamic Range, at the same performance and memory costs as standard 32-bit pixels, but comes at the trade-off of only leaving 2-bits for the Alpha channel basically allowing for either totally transparent, totally opaque and two intermediate values.
Although ATI have provided these HDR blending capabilities in the R520 architecture they haven't removed any orthogonally, meaning that all modes of operation that run through the ROP's work with one another, the net result is that all of the FSAA options that are provided under standard blending buffers are equally supported under any of the HDR blending modes, however the costs associated with the 64-bit modes and FSAA enabled are likely to be fairly high due to the bandwidth utilisation and memory space requirements.
