I have just replaced a GTX 480 with a 760 4gig card changing nothing else but now my from rates have dropped from 40 to mid 20s and lower. WTF. Anyone with any ideas??

Greetings all,

Reinstall your drivers for NVidia, there is a new WHQL set released on Sept 19 for 64 bit as well as 32bit.

Do a clean install to remove any "profiles" that may be saved for the 480 series.


Later,

I re installed all drivers. I have checked video card with GPUZ and all appears well with the card... so I have no idea. May just reinstall whole game and see what that does. Still very strange.

Nah, it is just MWO, my framerates are all over the place since 12 mans. Maybe DX11 will help. And yes, my power profile is set to performance and I have an I5.

Just checking here... but your PSU is strong enough to run the 760? If it is just barely able to support that card (under load the GPU could possibly not be getting enough power) maybe that is causing your slowdown.

That aside, what CPU do you have? Even though the game is released, the code is not optimised enough to take advantage of GPU as it is still very strongly reliant on the CPU (although that still does not explain why you have less FPS with a stronger GPU and the same CPU).

The rig is running a i7 at 3.4ghz and 12 gig ram it should be plenty with the GTX 760 to run this game at reasonable frame rates. As I said the frame rates have become more marginal with the better GPU.

Get the free driver cleaner I think cnet has it on there site, uninstall driver, run cleaner and install new driver Then run mwo repair tool then reboot system then see how it running. Be sure to run mwo and let it clean everything even you profile setting game might be thinking it still running on old card. Before you run mwo repair try game and see if problem is still there if it is do the whole repair tool thing of it fixed just do the standard repair tool thing.

A good driver cleaner would be driver fusion, for instance

Just to be sure, you have connected thos 6/8 pin Power cables to your GFX Card? Some of them start up without the extra power but they dont run very fast.

Just saying, happened to me twice already.

I've recently read it's a good idea to do this after every hardware and driver change: type "winsat formal -restart clean" into a command prompt, and let it do it's thing. (seen @ http://forums.guru3d...&highlight=EIST)

Have you tried deleting the shader cache?

Has you see the specifications of video card?? the 760 it's the lowest card in characteristics of gtx series, the 480 have a lot of powerfull. Maybe it's similar in processing power, bandwith, etc.

The game it's not be able to run all specifications of your new video card too.

It's my experience cryengine hates low mhz, even on an I7, but you've got that covered. I've never heard if cryengine has a hangup with memory bandwidth, or anything, so …

It also seems like cryengine hates Kepler, and the only thing Kepler reportedly doesn't do as well as Fermi is OpenCL/ DirectCompute: "gpu_particles_physics = 1" or 0 doesn't seem to make a difference, so I'm at a lose on this front. I keep hearing the DX11 patch will cure this, 'cause "Kepler is bad at DX9," but I'm not holding my breath anymore: The "suggested" swap to my old GTX580 has done nothing for me.

There's this funny thing with how only one core is really loaded when in a gun fight, but three cores are when in the training grounds; There's this other factiod on how the fps comes right up once you are dead, even if you're the first to go. Must mean something …

I think he meant "Power Supply Unit." For example to run two AMD Radeon 6870s with everything else I had, I had to have a minimum of a 1,000 watt power supply. Of course I expected it to run over 6 hard drives and a bunch of crazy stuff.

Takes a lot less power to run a 480 GTX versus a 760. His card's ram is identical to what I have on twin cards, so I imagine it'll require a good bit of wattage from his power supply.

I have the same card and before I installed it, I uninstalled all of the nvidia drivers first, ran PCTools registry cleaner, shut down, replaced card with new, restarted, THEN, reinstalled the most current drivers and get great FPS at max settings (always above 50) with vsync on.

Really? That's amazingly efficient. o.o; I want one now.
