The client has a problem in the code, it seems:

Code:

shaders/class1/deferred/alphaF.glsl didn't change between v1.26.12.22 and v1.26.12.23, and the only change in llshadermgr.cpp deals with a define for ATI cards, so it can't possibly affect your card.

Also, I'm not seeing any error here, using a GTX 660 or GTX 460.

My guesses are (in likeliness order):
  • Failure from the driver to properly use the cached compiled shaders, and/or failure to detect a new set of shaders: in this case, just wipe out your compiled shaders cache and restart the viewer to solve the issue.
  • Incomplete/buggy support of your driver version for the GTX 980 (wow, you like them ultra-fresh (and expensive), don't you ?...).
  • Buggy GLSL compiler in the driver (did you just update the graphics driver ?). Using 343.22 here, but under Linux.

In any case, I very much doubt it's a viewer bug and if after wiping out the cached compiled shaders you still encounter the same issue, then my guess is that you will encounter it as well with LL's release viewer.

Yup, much required, I use a 4K display plus a 2560x1440 display on my PC. :D

nVidia just updated the drivers again today (after a release last week). Will check if the problem still occurs.

EDIT: And I did a clean install besides the updated install and there was a difference in glsl files, some got removed, so I cleaned up a bit. That will probably help. :)

EDIT 2: Yah up, that did it. :)

I get only about 40 FPS or less on ultra (65 FPS on high) with a GTX 970

The graphics card doesn't even get hot, below 60C so fans stay off.
Shouldn't i get much more FPS with a monster card and CPU like this?


edit: I tried other viewers too, Cool viewer is the most fast viewer for my PC (of course)

A GTX 9x0 is an overkill for any SL viewer: a GTX 660 will give you equivalent results unless you got a super-high resolution monitor tied to it...

The bottleneck in your system is likely the CPU: even the fastest CPUs can't feed a GTX 9x0 fast enough to load it at 100% in a software such as the SL viewer, which uses a single-threaded renderer (i.e. the rendering code only uses one CPU core, and the speed will depend almost exclusively on the CPU frequency, not on its number of cores when they are beyond 2).

To try and get the most out of your CPU, you may enable the multi-threaded optimizations in the NVIDIA driver (this is done automatically by the Cool VL Viewer, under Linux, thanks to an "export __GL_THREADED_OPTIMIZATIONS=1" in the cool_vl_viewer wrapper script, but this must be configured at the driver level under Windows).

That's because the main loop code was optimized the most, giving more time for the CPU to execute the rendering code. It's important to optimize the code where the speed bottleneck actually is...

I don't know if you overclocked your CPU (it will keep reporting its default factory speed in /proc/cpuinfo under Linux, so what is displayed in the About box is not relevant), but if you didn't, your best bet is to try and do it (my Core-i5 2500K is overclocked at 4.6GHz, and it does make quite a difference when compared to the 3.3GHz stock speed).

Thats a weird comment, saying as if i bought the card pure for SL and should use an older card instead? Not.

That's the only valid reason i can think of yes, will SL use more core's in future?

Nope, and not really planing to.

It's not weird at all... I'm just trying to explain you that your expectations for faster frame rates in SL based on an ultra-powerful GPU are moot...

It's highly unlikely as it would involve pretty much a full rewrite of the whole renderer... Perhaps in SL 2, if SL 2 will at all use a dedicated viewer client software...

Why not ?... There's no risk doing it (at worst, you'll get crashes while overclocked and will have to run it back at stock speed), and only potential gains... Especially since your CPU is a "K" (unlocked) series ! I'm ready to bet that your CPU could easily run (with no or very very little supply voltage increase) at a minimum of 4Ghz, i.e. at the very least a 12.5% speed gain, and 4.2GHz (20% gain) is most probably a reasonable expectation with still very conservative (100% risk-less) supply voltage and max core temperatures for an Haswell (which is less "overclockable" than a Sandy bridge or even an Ivy bridge... Shame on Intel !... But Intel is a shame anyway, by its CPU's very flawed architecture... If only IBM had chosen Motorola (the 68K was gorgeous !... It already was a 32bits, flat-memory CPU when Intel was still struggling with 16bits and paged memory) instead of Intel for it's IBM PC platform... *deep, depressed sigh* But I digress...).

My GTX 980 helps me for using the 4K and the 2560xsomething display at the same time, as it helps with several directx games. :-)

One thing that's useful: for several software you can just disable antialiasing, pixels are small enough on the 4k display that you mostoften don't need any AA.

I didn't get it for Sl specifically. The overall opengl performance boost isnt that much of a thing usually. :p
