D-Scythe Posted December 9, 2005 Share Posted December 9, 2005 Well, ran a detailed benchmark of Bright Textures. Converted a preliminary batch, including virtually every city/airfield BMP texture, into 256 colour and tested it using the first 2 minutes of ED's column hunt track. Here are the results: Blue is normal, Purple is Bright. There is a little increase in average FPS, but not much. Here is the FRAPs log for the two data sets: Normal: Frames: 2116 - Time: 118280ms - Avg: 17.890 - Min: 0 - Max: 43 Bright: Frames: 2224 - Time: 120355ms - Avg: 18.479 - Min: 0 - Max: 43 The difference is about 0.6 FPS; it's nothing to write home about. Don't think it is worth converting every single texture with Bright, unless you got time on your hands. Link to comment Share on other sites More sharing options...
Jammer Posted December 10, 2005 Share Posted December 10, 2005 No surprise -- even though the "Bright" textures are 8-bit on disk, they are eventually converted to 8 bits per channel (24/32 total bits per texel) once uploaded to video memory. The only benefit these might give you is faster load times, and perhaps a little less stutter. On the other hand, converting all textures to a compressed DXTn DDS format (DXT1 for opaque textures, 1a for binary alpha, 3 for low-quality alpha, or 5 for high-quality alpha) would instead provide much reduced system and video memory usage, since they would remain compressed throughout the pipeline (HD -> system memory -> video memory), and a potentially significant FPS boost on some hardware. Believe it or not, but a compressed DXTn DDS texture consumes less video memory than one of these 8-bit "Bright" textures. Link to comment Share on other sites More sharing options...
Pilotasso Posted December 10, 2005 Share Posted December 10, 2005 This benchmark is wrong. LOMAN re-converted everything back to 16 bit in packing the CDDS.
