i upgraded my 4gig ddr2 800 win7 32bit system from dual core to quad core, and just added a 7770 OC gddr5 vid card,in testing grounds the game was stunning on very high settings but i would get a memory allocation error dropping into a match.i turned settings down to medium ,and run 35 fps when there are buildings and 50-60 fps on average.with the older system and the newer vid card can the vid card settings be set too high?there are sliders to adjust the vid card clocks.

my cpu clock is 3000mhz,my memory is ddr2 800, the vid card core clock is 1100mhz and vid mem clock is 1250mhz.

the HD7770 need at least a PCI-E 2.0 graphics slot

reason being the graphics bus lane is like an 4 lane highway to the CPU

installing a GPU on a PCI-E 1.0 = limit it to only a 2 way lane highway

pretty your system is max out its good use

might want to get a new system and use the HD7770 in there instead

Mate, MW:O is CPU dependent. get a new mobo, CPU and RAM - your video card is too much for your current machine. And DDR2 800 RAM - sheesh. I got rid of mine 2.5 years ago when I built my current system and switched to 8GB 1333/12800 DDR3.

Ok, I want to start by saying the HD7770 is not a high-end video card. There are just to many video cards from previous generations that out-perform the HD7770 for it to be considered a high-end card. It is nothing more than a lower-end gaming video card. For example, the HD5850 from 2 generations ago out-performs it by more than 10%, as seen in this chart-



Ok, now that that is out of the way, you said you upgraded to a quad core that is running 3ghz and you're running DDR2 800 RAM.. That tells me you have either a Core2Quad Q9650 or a Phenom II X4 940 CPU. What motherboard do you have? While both CPU's are capable of being strong enough for the performance you desire, some OC'ing will be required. If your running a Intel C2Q Q9650 system, I can definitely help you OC it to at least the 4ghz mark. I had a Q9650 system before my 2600K system. I ran that CPU at 4.25ghz for 1 1/2 years before the upgrade without issue. In fact that CPU is still in use today. If you have the AMD X4 940 CPU, I can still help getting it OC'ed to the 4ghz mark as well. Both CPU's would yield considerable performance improvements in MWO with OC'ing.

As for OCíng your HD7770, it is definitely possible. The easiest way for you to do this would be to go into your CCC, enable Over-Drive under the performance tab, and use that to OC for 7770. For the best results, I recommend you DL/install the OC'ing program Trixx produced by Sapphire. Another program you can use is MSI Afterburner, but Trixx usually yields better results. Using Afterburner, I could only OC my HD7970 to a core speed of 1075mhz.Anything higher would result in an instant crash once I started a benchmark or game. But with Trixx, using the exact same settings I tried to used for Afterburner, was able to reach a core speed of 1150mhz before any crashing would occur. You can find the Trixx program here- https://www.sapphire....com/ssc/TriXX/

In closing, just let me say that while OCíng will give you some performance gains, trying to run MWO at very-high settings with a HD7770 and maintaining high FPS (+50fps) is not possible. Yes, the 7770 is very capable of producing enough FPS for MWO to be playable, as you saw when you reduced the settings. But what you saw is about average performance for your HD7770. OC'ing will help, but you will not achieve very high settings with your current system.

The video card doesn't matter that much, it is quite adequate. The main bottleneck in MWO is the CPU, not the GPU.

As BarbaricSoul says, you want to clock your CPU to at least 4Ghz to have any chance of getting a stable 60FPS.
I would set everything to low (Make sure AA is off), then OC your CPU until you get a stable 60, then start turning stuff up to see what will not affect framerate too much (Unlikely to be everything, on my rig I don't run at max to maintain a stable 60)

[Barbaric Soul]

I can't 100% agree with your first statement EvilC. Yes, I agree the 7770 is adequate to play MWO, and yes, the CPU is the main bottle-neck when MWO is concerned. But expecting to be able to run VERY-HIGH settings and maintain +50 fps in MWO with a HD7770 I feel is a unreasonable expectation. Granted, the OP hasn't said what resolution he/she is running, and if he/she is running 720p or lower, 50fps with a 7770 may very well be possible. But very-high settings at 1080p or higher I don't think is possible.

I'm out of town until tomorrow, but I do have a couple HD7770 cards laying around the house. If you would like, I can put one in my 4.5ghz 2600k system and see what kind of FPS I can get. With a 7970, that system gets 45-60 FPS with very-high settings at 1600p. I can run the game at 1680*1050 and report my FPS with the HD7770, OC'ed and not OC'ed.

The 7770 is a decent GPU, but it won't play at high settings and yield good frame rates at 1080P.

My 5850 managed a combination of medium and high settings. If OCing the GPU is desirable, then Barbaric is correct, Trixx is the way to go. It lacks the features of Afterburner, but a given OC will be more stable with it, for whatever reason. Trixx gave vastly better results on my 7970OC. Still, take care of the CPU first

[EyeDie I]

im not trying to pin my fps to 60, im saying that it runs in testing grounds at very high but crashes when i try to drop in a match i get a ++++memory allocation some multi digit number failed +++ message, ive gotten it to run medium settings with 2 settings set at high, the top 2, objects and something.i am not in the game right now...,
thanks for the replies.

i would add the card is sold as over clocked, my question was more 'should i lower the settings closer to my bus speed?'

i feel horrible dropping and disconnecting trying to test settings that work in testing grounds.

oh, and compared to my 5450 with no fan, its high end )

No, no, your bus and GPU clocks have nothing to do with each other.

The problem with your GPU is that we don't know why it's crashing. It could be your PSU is inadequate to power the 7770 when it's factory OCed, but underclocking it draws little enough power for basic stability, or your GPU could be getting too hot because of insufficient ventilation. If you OCed it past the factory OC that it came with, you may also just be pushing the card too far.

At present, we just don't know, and suggesting solutions before the problem is understood isn't good. What I would do is get GPUZ and monitor your card. How hot does the GPU get? The memory? How stable does the 12v rail stay if GPUz can read it? (Try speedfan if not). For that matter, what is your case and PSU model?

The AA in here is rather light weight: You'll get way more mileage out of zeroing out the partials, setting shadows medium, and/ or shading to merely high (which is also what you do to post processing).

[Catamount]

Yeah MWO uses FXAA, which basically has all of zero performance impact. Do not ever disable AA.

[StainlessSR]

If your CPU was overclocked, you should get around 40fps with med settings. The error you are getting is due to MWO using too much memory if the error is [memory allocation failed for xxxxxxxxxxx bytes} it is due to the game wanting to use more memory that it is allocated (usually 2.5GB is allocated with 4GB of system memory and a 32bit OS). This can be due to wanting to run with higher settings than advisable for your current setup. You can use med or low textures to help stop this error, known problem. Also, what resolution are you trying to run in? full screen or windowed? For help you need to supply more information. What CPU you have as it can be several socket 775 cpu's (I believe you posted that you had a core 2 duo in a different post), what operating system you are running would also help.

TLDR: set your textures to med or low, should fix your problem

Really? I'd "decided" it was Subpixel Morphological Anti-Aliasing 2Tx (maybe 1Tx,) as it seems such an all-around solution for reducing the options down to on/ off …

And I called my mechanic and told him my car is green and I can't drive right now!
That noob couldn't help me at all. :-)

IRL help with hardware problems ist often far more helpfull and faster.

In his/her 1st post, the OP said they were running a 3ghz quad core with DDR2 RAM. There is only one 3ghz Intel Quad that can run on a DDR2 system, the Q9650. They also said they are running Win 7 32bit

SMAA is in CE3, and I hadn't considered that, but it doesn't look like MWO features SMAA, nor does it default to FXAA, so I guess we were both wrong. According to Thomy's CryDev Blog, MWO defaults to use of something called post-MSAA that just saves every frame and blurs it into the next (how? I have no idea; but it looks good). FXAA is there and can be enabled it looks like (user.cfg?), but CE3's FXAA is outdated and bad, so there's no reason to turn it on.

There is a takeaway, though. PostMSAA is even cheaper than FXAA. So the moral of the story is, even more than I thought, DON'T EVER DISABLE AA

[TheNose]

So why is there a Txaa dll in the mwo bin folder?
And if you take a look at systemoverride.cfg Txaa and Msaa are set to 0, but postaa (edgedetect) is active.

whatever it actually is, true is what you said:


DON'T EVER DISABLE AA

Edited by TheNose, 31 August 2013 - 06:50 AM.

[Catamount]

Well according to the above development blog, post-MSAA is a modification of temporal anti-aliasing, so that may be why. Post-AA here is apparently not edge-detect, however, at least not as I understand it, because that's what FXAA is. My Systemoverride.cfg also makes no reference to the edge-detect filter.

All it has is
