Best guess
In most games the GPU is the more important part fps wise
Even if you can't reach high fps if the CPU is you're bottleneck you can still enable AA n some other features that are not as CPU dependent


If you have the cash for only one thing, then the GPU might be a better choice

Yeah all true but then I wouldn't start a thread like this, when using such an old CPU. That top notch AMD rigs perform below their expectations is another issue.

While you're right I guess there's also no reason(well a good one) for MWO to run relatively bad on modern hardware
I would expect it to run like in the testing grounds, fps triples or even quadruples compared to live matches

it was said that the dx12 upgrade would automatically loose dx9 support (CryEngine in that regard)
That's the reason why PGI has not pursued dx12 quite yet
Because graphic cards older than 5 (or is it 6, hard to remember when we had dx9 only cards; dx11 cards would be fine) years couldn't run this game any more

And the general section is the place to vent, but also gets more attention when looking for answers than the other sub forums

This seams to be an issue with modern AMD CPUs and MWO, older AMD CPUs perform in the range you would expect considering they are old.

My AMD Athlon II x4 640 runs the game stably at 70% load on all four cores, apparently for me it's the HD6770 that bottlenecks the game into 25-50 fps range at mid to low specs.

That's not an AMD problem, that's an MWO problem, it performs like dogshit on all mid-range CPUs.

As much as I want to say "get an Intel, AMD scrub," this is also a really good point.

I have to add my system to the wonky AMD support for MWO. I have had issues with performance since they introduced 12v12 and I have had several upgrades to my system over the years of playing.

As it stands right now, I run a mixture of very high/high/medium settings with a resolution of 1920x1200, the FPS tends to be all over the place, I can start a match after the initial mech power up and have 100+ FPS and sometimes dip down below 30 FPS, it gets even worse in CW for some reason with dips as low as 15. Most of the time it is playable but there's some situations where it just shouldn't be that bad with my system. I've seen FPS dips during combat and I've seen dips just when looking certain directions on certain maps before even meeting the enemy. Also all the new, reworked maps, Caustic, Forest Colony, River City have about an average 20 FPS lower than the other maps.

I can play pretty much any other game maxed out or nearly maxed out at 60+ FPS with my rig with no issues. I've done numerous tests with performance, temperature, and graphics settings. Over the years I've found out there is hardly any difference in performance on average between all settings on Low and all settings on Very High. The only difference is the maximum and minimum FPS is higher or lower, the average is within 10 FPS of each other. Another thing is the game pretty much doesn't use more than 65% of my CPU or GPU at any point.

System:
AMD FX-8370 8 core 4.3Ghz (just got a water cooling system for it, going to mess with overclocking it some after the new thermal compound sets)
16GB Mushkin 2133Mhz DDR3 SDRAM with 9-10-10-28 timings
ASUS M5A97 EVO AM3+ Motherboard
EVGA GTX 770 Superclocked ACX 2GB
and the game and OS are on a Samsung 840 EVO 120GB SATA III SSD
Windows 10 Pro

I have the exact FX 8370 and dip in the exact same way. 100+ fps runs easily around 70-80 fps, with inexplicable dips under 20 fps. In cw, I'll sometimes dip to around 6-7 fps. We have the exact same problem in the same chip, so you're not going crazy.

I gave up. After trying every fix suggested by mwo players and random forums, I am giving this pc to my five year old to run minecraft. I just bought a new I5-6600k. Fingers are crossed.

It's a CryEngine problem, not to mention AMD CPU's are garbage for single threaded games, which is why games run poorly on AMD processors as well, since they are designed to multitask more effectively than an Intel CPU, but clock for clock and core for core, Intel still makes AMD their whipping boy and AMD doesn't invest near enough to rival Intel in their CPU development. Most of the problems on AMD processors are tied to CryEngine being poorly optimized and being CPU reliant, and not optimized for multithreading.

There are MWO AMD CPU problems (meaning something about the engine and game-design/build are not working with AMD CPUs) and I have been trying to get support to deal with it for a while. They have me trying new graphics drivers -- but that won't solve the underlying issue -- the game only appears to use 2 of my 8 cores for almost all of its processing. That causes some pretty substantial bottle necking. I sit at around 60 fps on the lowest settings and every increase in visual beauty will give me a 20 fps drop.

This is my MWO potato:

Processor: AMD FX9590 8 core @ 5Ghz (Overclocked and liquid cooled)
Graphics: 2 AMD R9290x 4Gb ram @ ~2Ghz. (Liquid cooled overclocked)
RAM: 64 Gb (so much -- for work related reasons)
HDs: Stripe set of intel SSDs.

edit:
I have gone so far as to run the game on an entirely separate SSD array with just the game and teamspeak on it (nothing else but the OS/drivers installed). It's frustrating and making me consider a new mainboard and CPU/water block for Christmas.

I have FX9590 + 990FX UD3 MB + R9-290X 4GB + 128 GB SSD + 1 TB HDD + 16 GB RAM and I run the game on maxed settings with min FPS of 50-55.

CryEngine is actually one of the better engines for AMD CPUs, if you compare Crysis 3 results, AMD CPUs perform as well as equivalent Intel CPUs in most respects.

The reality is...MWO is not well optimized comparatively; however, my AMD system runs the game significantly better than some are reporting, leading me to think that there must be some other issue...

Typically, do everything you understand on that list...

The other thing for AMD CPUs, is to slightly overclock the northbridge to around 2600 MHz.

Aside from that...you wasted money upgrading now...

Yep -- why do you ask cSand? I could easily throw another HD in with a different OS -- what do you suggest?

[Illuzian Pryde]

Try turning all your graphics settings to max if you have a decent GPU, for MWO this often takes the processing off the CPU and onto GPU.

AMDs are pretty notorious for their poor single threaded performance though, even at high end they've focused on more cores vs single threaded performance so I hate to say that at least for MWO(or any other CPU bound game), your mileage will vary considerably.

[nehebkau]

I am just resetting my system performance to stock values and then going to log an entire game for PGI so they can see core and graphics usage... ill post a link to the graphs here.

Running ultra?

[Johny Rocket]

Win 7 x64
Run client in 64bit

FX 8130 slight OC using stock bios profile

MSI R7 265 Armor OC edition 2gb GD5 same level OC as CPU

I have no issue running the game on High/Very High, I run it on Medium because it reduces things like the flash from exploding missile and cannon shots.
