FWIW - bsim racing blog on poor nvidia image quality

I know nothing about computers and this stuff is over my head...
I am not sure if this applies to Assetto Corsa, but some people are finding problems with Nvidia graphic quality in newer cards as compared to older cards.

Im getting pretty darn good IQ out of my titans, there are lots of things you can do to bugger up the IQ and most likely many do this and get poor results. If you know what your doing you should be able to get good images and performance. Some games and sims will be pretty badly coded or drivers dont work properly as in RF2 with sli but everything else looks great and performs well.

The funny thing is that rf1 and all games based off that look amazing and performance is so good on my setup. Then go to rf2 which really doesnt look much different to rf1 graphicaly just with broken hdr and some extra features. Using the default rf2 sli profile goes from 70 to 100 fps single card to 35fps in sli lol.

If you make some changes in the sli profile then you get some ok performance but hdr is broken with flickering and also the reflections so fps must be capped to avoid this. Really one of the main reasons i stopped running that but also the ac driving physics are way better onoy the karts have any real rubber tyres there so far the rest run on marshmallows.

 

AC looks pretty good but I do recognise the blurry distance textures and ailiasing issues....

 

good lord! so that's what's going on! wow what a bunch of incompetents. they really outdo themselves every time. real shame that they have the only viable 3d tech. how they even came up with it is beyond me.

count on me to send them a bug report every single day that this isn't fixed.

 

Seems like NVidia's not responsive to fixing settings like this...

One of my monitors is through HDMI and the drivers stick it in 16-235 TV colourspace instead of 0-255 PC colourspace, which completely washes out the blacks. There's no way to put it back in the right colourspace via the NVIDIA Control Panel, and the issue applies to every TV-resolution display (so 1920x1080, 1280x720, etc.) connected through HDMI. If your monitor only has HDMI inputs, or you're just using it cause you have triples, and you don't use this workaround, it's impossible to make your display go true black.

Even if you are using an HDTV, if the TV is expecting 0-255 colourspace, and some do, you'll wash out the blacks. It's just stupid to not let you change the setting. NVidia's line is that it's the monitor's fault for implementing the HDMI standard wrong, but... that doesn't solve the problem.

 

That article does make a lot of sense.

A few years ago running in game 4x aa sorted almost all ailiasing issues, now even 8x aa doesn't touch it. I had noticed that although overall performance is better my IQ had got much worse over the last couple of years.

I had put it mostly down to the console influence in games development and poor optimisation. Not so it seems. Nvidia seem to think that PC gamers are all only interested in raw fps at the expense of IQ. Some are I'm sure but I think many more are interested in a balance of IQ and FPS.

 

that's the worst thing: I don't think there is any known relation, performance-wise, between clamping and no clamping, it's just an alternative rendering method; one that is indeed highly favourable in the case of long-distance rendering environments, like racing games.
