nVidia Control Panel settings ignored by TS2014

NVI uses exactly the same settings as the NVidia control panel it just "unlocks" the ones that we can't see in the control panel.
One caveat don't alter AA, AF, Vsync, Pre-rendered Frames, in the NVidia control panel AFTER setting in NVI as they will be overwritten.

Did you use OVERRIDE or ENHANCE in NVI?

ttjph- You're most welcome, I'm glad you found it useful

Here's a question for you Peter, any idea how I can override texture filtering in TS? I swear the ground textures are blurrier now than TS2012 for example. I guess another good one would be to get LOD bias working. But no matter what I set either of those to in NVI, it just doesn't affect TS14. I've had a look through the shaders and recompiled some of them before, will have to take another look I guess...

A great question but very difficult.
I have found that the textures vary from route to route ie some clearer than others.
AS I say above the clearest textures I get is with TSX off but then the colours are washed out.
You could try NVI as suggested by Deltic - ie turn off all AA/AF settings in TS2014 and then use NVI
AA Gamma Correction - ON
AA Mode Override the application setting
AA setting to 16xS to match the 4 x SGSS setting (or 8xSQ to match 2 x SGSS setting)
Texture Filtering LOD Bias set at clamp and Texture Filtering LOD BIAS (DX) at -1.000 (with 2 x SGSS set at -0.5000
AA Transparency Multisampling try enabled and disabled
Toggle FXAA on or off - OFF
AF setting x 16
Max Pre-rendered frames (default 3) try every other setting to see which gives best results - I'm using 6
Vsync use adaptive at half the refresh rate.

Finally downsample your monitor using NVIDIA Control Panel to somewhere around 1.2 to 1.5 x the default resolution (and set TS2014 to use that resolution) See here: http://forums.guru3d.com/showthread.php?t=346325
I can't guarantee anything but these settings should give a clearer picture.

Thanks Peter I will give that a go! I unfortunately am unable to downsample my monitor, as it runs at 2560x1440 native, and doesn't seem to accept any higher resolutions

Sorry, forgot to mention if you get multiple screens with these settings - change the override in NVI to enhanced - forgot that!!

I have exactly this same issue with my native resolution of 2560x1600. It is simply not possible to 'downsample' when the native resolution is that high, or so it seems.

I wouldn't be surprised if it is a data rate restriction of the monitor cable, I'm not able to down sample from as high a resolution as that to my native 1680x1050 on a 650Ti, anything above 2500 and it fails at preview/test stage and both of your resolutions are above what I've tried. I am aware that some people are down sampling from double full HD on full HD monitors.

It could be the cable but its more likely to be the VRAM on the card with a resolution of 2560 x 1600 with TSX on you would be using around up to 2GB VRAM so any higher resolution would need a powerful card eg Nvidia GTX x80 with at least 3GB VRAM and 4 GB would be better. On my 1920 x 1200 IPS monitor, 2GB VRAM with a displayport connection I cannot get beyond a downsampling ratio of 1.4 ie 2688 x 1680 (1.5 won't work - 2880 x 1800)) and at 1.4 x I am using 1.9GB VRAM in some scenarios/routes.
At a resolution of 2560 x 1600 you are rendering 123 MILLION pixels a second @ 30 fps and the needs a lot of oomph and VRAM.
In downsampling my cpu usage rises only very slightly, RAM is constant, FPS falls (frame dwell times increase) showing the load is mainly on the video card.

Peter,

While VRAM is certainly something to think about, as I've mentioned in previous posts I'm using a GTX 680 with 4GB of VRAM, so have plenty to go around.
From what I've read online its most likely just too much information to be sent via the connection.

I also tried out the settings for NVI you suggested, unfortunately they had no effect in the sim.

[deltic009]

Yeah, I'm with Jordi on the VRAM point, I'm able to do 2520x1575 at 60fps (when its quiet LOL) on my machine and that's with a 1Gb 650Ti card.

[peterfhayes]

Good comments but I am seeing with TSX on and settings set inside TS2014 (enhanced by NVI and NVCP) significant amounts of VRAM being used.
I see the point about the cables (up to a point) , I wonder how they get round that for 4K HD screens where the data flow is many more times than the resolutions we are using?
So it could be a DVI issue- early HDMI cables can deliver 2.2 Gbits/s (are we exceeding that in downsampled TS2014) and the later cables deliver 10.2 Gbits/s.
So as anyone used an HDMI cable to see if that makes a difference?
I use a displayport connection with a bandwidth of 17.2 Gbits/sec so that should not be an issue for me?
Thanks for the input.
