Have you checked it with GPU-Z to make sure it's functioning correctly?
Have you run SHoC totally vanilla to bench mark FPS (including useltx "Vanilla".
Then run it with your gamedata and settings (user.ltx)?
I have a 60 FPS difference between vanilla and my mod with an ATI 7970.

You don't think 750w is enough for his system? Have you been smoking crack? It's more than enough.
I have a 650w supply and I'm powering more stuff than he is in his system.

That's exactly what i think.

Have you been smoking crack?
No, but i have been smoking other things...

No, it is not.

In that case, you don't have a computer for modern games. Well, if you play Pacman... That's ok.

Yes I have, according to that everything should be fine. However AFAIK GPU-Z shows only the actuals specs but is not a function test.

Yes I have, and yes the difference is huge. But as long as I have no means to compare my vanilla FPS to the one to be expected on a rig such as mine, that doesn't help me.

All I can compare atm are the FPS values that I'm having now with my GTX560Ti and had before with the GTX260. And THAT difference should be huge IMHO, but it isn't. It's almost the same.


EDIT:
What about video memory? May some mods (or my shaders) tend to "flood" the GPU's RAM so that the card couldn't handle any more texture data? Because after what I've read in forums on other games that is a typical reason if performance becomes incredibly bad.

If your shaders are intense, that is possible. I had a huge difference between 896MB and 1280MB when running NS DMX.

Guys, many thanks for all your hints.

BUT: Is there a way to verify that my GPU itself is ok? I mean, I already tested quite a lot of those things suggested here and haven't got any further, so before I waste any more time struggling around aimlessly in the miseries of my rig I'd like to be sure that it's not "only" the 560Ti itself that is somehow messed up / broken. So is there some tool or something helping me to verify the graphic adapter itself is clean and working?

---END QUOTATION---



you could use a benchmarking tool like FurMark and let it run your card under high pressure and look if there are artifacts or graphic failures happening, it should have profiles of similar systems to compare the FPS too

also Cuda Memtest could be helpful to check your cards memory

or this one, it shows errors on the run

The older cards have bigger bus ratio's allowing for better data-transport. A 448bit interface really does help in delivery of the data, while a 560ti IIRC only has a 192bit interface, leaving it with less data lines. There's been a huge downgrade since the 400 series, only because the cards would become too hot iirc. Trust me, if you compare a 512bit interface card with a 192 or 256 bit with all of the same specs, the 512 is going to dominate the rest. At the time the GTX290's were the kings of everything on the market. Sadly they stopped doing that for double GPU cards, only the top of the top (not even the TITANS)

I play Crysis 3 and Battlefield 3 at high settings on my mere 650 watts system...

I'll leave it at that.

Please educate yourself.

LoNer1...the 560ti has the 256 memory bus but I know what you are saying. I've also been worried about the reduction of the width of the bus since the newer GDDR5 memory is faster in speed so they want to use the speed of the new memory to go through the narrow bus. They originally used the wide bus for the GDDR3 slightly slower VRAM. My GTX 470 & GTX 480 both continue to play all games well to this day. Those have a 320 bus & a 384 bus.

I still think Meltac should see a noticeable difference in frames.

Yes I should. All your suggestions might be worth a try, but they don't explain why the GPU showed double of the FPS in the first test run that I'm having now

It all started (or ended, put it the way you like) with updating the old driver from the card's driver CD to the latest downloadable driver - From that point FPS was only half of what it was before.

The strange thing is that all these clean-up procedures such as running a clean driver installation and using tools such as CCleaner, DriverSweeper, or TuneUp Utils doesn't help! Once the initial performance was gone, it could not be restored by any means!

THAT's the point of all. Unless some HW component such as the PSU or the GPU itself became broken during the driver update, there's absolutely no reason why checking system specs or running benchmarks could help anyhow - instead, identifying what happened during the driver update and how it's fixable is the solution I believe.

As a last resort - have you tried re-flashing your bios? It could have been corrupted by the new driver. EVGA had a thread where you could request an updated bios. They'd stopped releasing the 580 bios so I was unlucky but other Googled site's had them [if I remember correctly] My problem [fan speed throttled back] made it not worth the risk to use a non EVGA site bios.
