I'm tempted to tell Optimizer to do DXT5 instead unless this isn't noticeable in-game.

Is there really a big difference between and res textures? Is this a noticeable quality change? I saw the comparison image on optimizer's nexus page and the DXT1 looked more blocky.

Please re-enable javascript to access full functionality. It claims you can use a texture in the otherwise blank channels to reduce artifacts, but then claims artifacts will be greater than if these channels were blank.Jump to content. Maybe do-able, you would need a graphics programmer.Д®ven our own polycount page seemingly makes a brief mention of this though with a bit of contradiction in its phrasing. If you don't recompress, you still would have to fit the extra G data into the compression range allowed for that 4x4 block.Дefinitely beyond my knowledge, and I probably have some things wrong here. If R and B contain blank values, then G can be compressed more accurately. Colors can only be stored within a certain radius around that line. Think of the RGB channels as levels in a 3d chess board, and trying to draw a line connecting each. So if the values in R and B are different from G, then it has to expand its range to encompass them all, which means each channel gets lets precision in the end. All three channels have to use the same offsets for each pixel chunk. The compressor makes a vector through all three, and computes the offsets needed to store each. The way I understand it, DXT compares all three RGB channels for each 4x4 block of pixels, in order to compress them down to a smaller range of colors.

How to bypass payment gateway in website 2018 Sprunghunt, yes, thats my plan personally, but I need to find out about this specific inquiry for a dxt5nm implementation. I will go and edit original to make more apparent. But a game engine has to take advantage of this to work.ДЄgain, if I'm reading the Nvidia article right. The writing I have found seems to imply you can use at least one of these channels to compliment the green channel of the output to give a better range than it would otherwise from the lower bitdepth. I am specifically talking about the red and blue channels in the dxt5-nm itself. I know dxt5nm puts the red and blue in the original to green and alpha in the swizzle. One of these should end up looking very 'green' because the red and blue channels are empty black. There's not trickery about storing data 'across' different channels to get a higher bit-depth or anything though, not to my knowledge. Because DXT compression does a less shitty job compressing those channels, and because the colors from the two won't get blended together so the values are more 'true'. It's just taking the data from the red and blue channels, and moving it to the green and alpha channels. The artifacts will be greater than if you keep Red and Blue empty, but it might be a tradeoff worth making. Instead of storing a bias and scale, one of the spare channels can also be used to store a rotation of the normal vectors. Then combines it with the output green channel to give a slightly better bit depth than otherwise.

Jul I am not having any confusions about the swizzle of red and blue in the original file to green and alpha in the output dds. While you can use ENB to extend the vram using system ram, now you're making the system swap textures in and out of vram, and resizing the textures is again better since now you don't have to swap as often, and the textures being swapped are smaller, making them faster to transfer.Toggle navigation Polycount. But if you don't have at least 1GB of vram, you really need to scale the textures down, especially Skyrim.

It's vital to reduce the textures in size or you run out of vram too fast, limiting how long you can play before textures start disappearing. The point of scaling the textures isn't to make things faster, since it doesn't, it's to use less video ram on cards with less vram, or especially with systems with shared memory, like Intel or AMD integrated video.

After scaling the textures, it's best to install a book/note texture replacer, or to not override the original book/note textures. The only issue I ever saw (and I used it for everything from FO3 to Skyrim) was that it made books/notes harder to read.
