Doc. Caliban Posted March 15, 2007 Share Posted March 15, 2007 Hello, I am running GR1 on a modern gaming laptop @ 1920x1200 with all graphics options at maximum. While I do have "Mipmap Textures" & "Compress Textures" enabled, I'm not entirely sure that I should. Can someone give me an explanation as to the purpose of each of these settings? Also, looking in OPTIONS.XML I find the following setting: <MipMapLODBias>-0.500000</MipMapLODBias> Can this number be "tweaked" for better results? I'm simply trying to get the best possible graphics out of the game since I'm running it on a late-model computer. (Frame rate is not a problem, I'm looking for maximum quality.) Best regards, -Doc.

Hammer Posted March 15, 2007 Share Posted March 15, 2007 A Mipmap is a series of images at different resolutions, So if you are close to a building it uses a high res image if you are further away it uses a low res image So it uses less PC power to render details you can realy see, But IMO it makes for a fuzzy image and i have them turned off My system is 2.4 dual core 2GB ram 7950gt 512Ram card All GR setting High, Mipmap off, shadows off, The shows are off though for personel prefernce.

Doc. Caliban Posted March 16, 2007 Author Share Posted March 16, 2007 OK, so what I'm taking away from this is that if I disable mipmaps, I will have high res textures at all distances. Correct? -Doc Quote Link to comment Share on other sites More sharing options...
Hammer Posted March 16, 2007 Share Posted March 16, 2007 Technicaly yes, But it would depend on your system ?? The best thing to do is fire up the game make a note of your current setting the experiment and see if you find something better. From what i remember about "Compressed Textures" if there turned on thinks like the command map and opions menu appear smaller on screen.

Doc. Caliban Posted June 16, 2012 Author Share Posted June 16, 2012 (edited) Long time, no see! I'm back to the game and introducing two new buddies to the title via co-op. Fun! I had to come back here to find out, once again, what mipmap and compression do because I'd forgotten, and lo and behold, I find my own thread about it! OK, I'm clear on the mipmap thing, but the "compress textures" option is still a mystery to me. What Hammer described is the "scale HUD" and "scale command map" options in the game settings. The "Compress Textures" option in the graphics settings is still a mystery to me. Anyone? -Doc Edited June 16, 2012 by Doc. Caliban Quote Link to comment Share on other sites More sharing options...
RileyFletcher_01 Posted June 16, 2012 Share Posted June 16, 2012 Don't quote me on this but I think it does what it says, compressed them. Without that option selected it is a bit grainy but when you do that they are much smoother. Quote Link to comment Share on other sites More sharing options...
Zeealex Posted June 16, 2012 Share Posted June 16, 2012 (edited) Games, these days espescially, have high resolution, high memory usage textures at least somewhere, and what texture compression is, is the storage of those high resolution textures in a compressed form (very much like that of file compression to a zip or a rar format) it lowers the resolution and the file size, when the LOD is needing to be higher, i think Don't quote me, the game's engine will decompress the texture and you will get the HQ image up close this allows the game to render the textures more quickly and without using as much RAM and without putting too much of a load on the GPU. that's how i figure it at least/ Edited June 16, 2012 by Zeealex Quote Link to comment Share on other sites More sharing options...
ApexMods Posted June 16, 2012 Share Posted June 16, 2012 The texture compression in GR is used to limit file size during authoring (not used, AFAIK), and to avoid bandwidth bottlenecks during rendering, as the reading of large texture files and shoveling that data into the graphics pipeline can be time consuming and may lead to hick-ups caused by either insufficient data read speeds (slow HD, slow data bus) or insufficient video memory bandwidth (texture data isn't moved quickly enough). From what I recall, Ghost Recon uses lossless compression and decompresses the textures on-the-fly during rendering, so the compression is never actually seen as image quality degradation or artefacts in-game. Through texture compression some graphics workload is shared between CPU and GPU so a fast main processor can partly compensate shortcomings in graphics card performance. Depending on your system, this can improve or worsen overall graphics performance. In general, if you have a relatively fast CPU and relatively slow Gfx, using compression may be beneficial, if it's the other way around (it rarely is) then you should probably disable it.

Doc. Caliban Posted June 30, 2012 Author Share Posted June 30, 2012 Thank you for this excellent explanation! This has helped a great deal. -Doc Quote Link to comment Share on other sites More sharing options...
