So I've been experimenting with this new tool that allows me to automatically downsample my resolution from 2560x1600 to 1920x1200, meaning I get all those pixels scrunched down to my standard resolution giving me really clear textures and much improved graphics overall. It does take a slight performance hit when I manually downsample, but with GeDoSaTo I've been able to maintain 40-60fps at 2560x1600. I was able to get higher that that, but then fps dragged at 20.

If any of you are familiar with downsampling, or if you're curious and want to try it out, GeDoSaTo makes it fairly easy to do. Just configure the ini for your intended resolution and then your present resolution, and it does the rest.

There are a few other options you can play around with, ambient occlusion, etc, but I'm still learning that bit.

IMPORTANT: If you downsample, the overlay for the buttons will mismatch slightly down and to the right unless you change the mouse position and reporting settings all to "True", then it will compensate, and all the menu buttons will work.

GeDoSaTo or Generic DownSampling Tool was created by game modder 'Durante' to help optimize games like Dark Souls 2, to give amazing graphic improvements. But he also intended it to be able to work with other games.

Some sample shots, compressed, so they don't look quite as good as the 6mb bmp file...
note: I have settings set on medium but more powerful cards can definitely get much better performance with higher detail

More info: I was playing around with it a bit more and found some issues with windowed mode.

Right now it doesn't seem to support windowed mode, it crashes. I tried full window instead of fullscreen and the resolution was sort of exploded to full 2560x1600, meaning only the bottom corner of the screen was visible on my monitor. I was able to return it to normal by changing the user xml file back to 1920x1200, but just a warning: right now it only works with full screen mode.

I believe windows mode and universal mouse tracking are in the works for later versions, so eventually this will be perfect for MWO right out of the box. But even so, with a little configuration, I'm really happy with the results. Some of you have probably tried downsampling manually via the graphics options of your OS, but this skips all of that, with a performance boost.

now... of course... you do realize that both NVIDIA and AMD give this to you for free as FXAA, right?

as I understand it, this uses different processes than driver based post processing, and it also gives some people a bit of a performance boost, and it's also free. So what was the real question again? Why should you use it? Because? For some people it affords some real flexibility with their downsampling and post-processing, and if you have the know-how you can use it to experiment with injectors and shaders.

No

downsampling renders the game at a higher resolution, then scales it down for very good quality images at a high performance hit.

fxaa runs an edge detecting algorithm, blurs it, then sharpens it agian, ****** image quality for reduced jaggies. It's not even antialiasing.

with nvidia you can do something similar, by setting scaling to gpu, then creating a custom resolution higher than the screen resolution.

No supprise, I have been using this trick for a while now in the screenshot thread.

Yeah downsampling itself is an old screenshot porn trick from way back. People have been doing it for years to get those amazing Grand Theft Auto shots at insane 8K resolutions. The games are sometimes barely playable, but they look beautiful. But downsampling with the driver configs can be tricky or unresponsive depending on your hardware, so this guy decided to make a generic app that injects the same instructions but through different methods, this gave the predictable result of being universally compatible, but it unexpectedly came with a performance boost* in comparison to doing it all in your control panel with custom profiles and using the built in FXAA.

*in some situations. so basically it looks like digital art, but it doesn't crawl at 10fps because you're at those higher resolutions.
