I've got an MSI built GTX-650 and have no real complaints. Overclocking with Afterbuner using arbitrary clock speeds just causes driver hangs (i dont have the patience to learn the math on how to set correct clock speeds). After using the GeForce Experience tuner, I get around 30-35 fps with most settings on 'very high' @ 1080 resolution. Setting to 'High' on all categories only yields about 40-45 fps for me, and at 'medium' I get about 35, which I find odd, but whatever.

The only difference between OCing a CPU and a GPU is that GPU's are a bit more of a PITA to 'fully test'.
For example u can go to far and the GPU drivers crash due to GPU instability, but u can get to a point where they dont crash but u get artifacts and the only way to check for this is to use ur eyes, and each game/bench program can show different results. Some may not show any artifcats whilst others will, so it takes a while to fully tune a OC on a GPU. BUT they are alot simpler .. GPU clock ..Vram Clock, and votlage ..thats it. CPU's have ALOT mroe options to tune.

CPU's are easy in the 'test' phase, just run ur chosen test program and let it be.

Gtx 780 and i7 4770k, i get 70-120 fps. And thats maxed settings. Running latest Beta driver.

Ok, got MWO to run nicely again on my 680 GTX:

1) Rolled back driver to latest WHQL certified.

2) completely uninstalled and reinstalled MWO (used to do this after every patch, but got lazy for the last few patches).

70-120 is excellent, but pointless unless you have a 120Hz monitor.

I do have a 120hz monitor

And to OP, why are you running 1333, dont that cpu natively support 1866 ??

Since he's not running an APU, it makes basically zero difference one way or the other.

[GrishdaFish]

Im running 1333 because I havent gotten around to upgrading my ram yet. There are other priorities to performance than a minor increase due to ram. Its on the list, but first is a SSD and a larger case.

Anyways, the problem is only slightly fixed. I get about 30-40 fps ingame now, regardless of streaming and settings. Only about 25% GPU usage and 30-40% CPU usage. Still makes no sense. I fired up Crysis 2 and have everything cranked up as high as it goes and I get around 100 fps constantly. This game is no where near the graphical fidelity of that game, but runs at a 1/3 of the speed. More tweaks inbound. Ive already made it Large Address Aware, its made almost no difference. I may roll back to the newest non beta drivers and see if that helps. Ive already cleared the shaders. Hopefully I can get the expected performance. I want 60 fps constant, regardless of whats going on in the battle, which I know I can put out.

[Catamount]

Since the increase in performance due to RAM would be zero in 99% of software (and nearly zero in the rest), and given the increasing prices of RAM, I wouldn't bother at all unless bragging rights are important.

I run a CPU that's -slightly- faster than yours in current games (3570@4.2ghz), and my system behaves the same whether my RAM is running at 1333, 1600 or OCed to 1800+ Even in benchmarks like 3Dmark the gains are smaller than the margin of error of the tests. Even back in the DDR2 days, there wasn't a significant difference between, say, DDR2-800 and DDR2-1066, and I had both. RAM speed hasn't mattered since the DDR1 days, back when we debated running DDR-400 at 2-2-2 timings or DDR-533 at 3-4-4 timings, and it still managed to make a barely-measurable difference either way.

There is little evidence to support higher clock RAM improving FPS.

[GrishdaFish]

Exactly. I already have 8 gigs, I never find any applications using all of my ram, there is no bottle neck. I do plan on getting better ram, but there is no reason to right now.

Anyways, official and beta drivers have the same performance and I can only seem to get a steady 60 on low settings. This is pretty stupid.

MWO is HUGELY CPU bound. I recently upgraded to a 7970ghz from 2 gtx 570s, and I saw absolutely no performance difference. However, I had previously upgraded from an i7 @4ghz to an i5 @ 4.8ghz, and I saw my min frame rate jump up by a good 10 frames.

first off...MWO doesnt have a 64 bit client...so u are using only up to 2gigs
secondly PGI doesnt use their sponsors enough (nvidia crytek)
thirdly they need an actual c-bill sale...its ******* launch

AMD are now the sponsors of Cryengine and not Nvidia.
Also try updating your drivers.....You can't just put a GPU in your system and not update it....

[Dizzmal]

I don't have any problems with my EVGA 780 Classified and I am running max settings @ 5760x1080 surround. The last update did make the FPS dip a bit though. I'm only getting 60~75FPS with some drops into the 50s at times now where it used to be up to 90~115.

Mine's an MSI GTX780 OC card. Not much issue other than very bad frame rate drops due to my old CPU first gen i7.
Do check whether your PCIE speed has been Throttled to x1 instead of x16.
Reseating the card usually first that I hear.
GPU-Z can help check on the PCIE speed issue.
