Bottlenecking or just bad optimization?

Thomas_Jefferson · May 9, 2014

So I tried playing arma 3 and got 7fps on ultra @1920x1080 and only 20-30 fps on lowest settings @1366x768, tried tweaking but these are really low for my system imo.

Spec:
Gtx 760 2gb GDDR5
Amd FX 4100 quad core @ 3.6ghz
4gb ram
550w unbranded psu.

Should I upgrade or is this just a freak problem?

Thanks in advance.

Slight bottleneck and bad optimization. You would want an Intel to run arma3. Also be wary of your unbranded psu. If it is a generic brand power supply, it can fail and take your hardware with you. If you are going to upgrade, change psu first.

the next upgrade would be your cpu, and is your cpu hitting 100% usage while gaming?

Danbuscus25 · May 9, 2014

yes, the psu does need changing

Yeah. Arma anything is pretty rough on any video card setup. And it's not that the graphics are better than those in other games either. I have to think there are some real inefficiencies going on in the code.

FX 4100 is a bit slow for Arma, but not 3-7 FPS slow.

Something is FUBAR. Check drivers, heat, CPU & GPU usage.

Hi, thanks for replying.

I just checked it and it's interestingly staying around 60% usage.

Yeah I was going to upgrade before I went from a 460 to a 760 but to be honest I've never had any problems even when overclocking, I'm going off the http://extreme.outervision.com/psucalculatorlite.jsp

and so far I'm nowhere near max voltage

Yes i knwo 550W is enough but the quality of the power supply may be bad. I just telling you to be wary of what your power supply actually outputs on the 12V rails. If it doesn't have a sticker stating what the amps on the 3.3 ,5 and 12 rails then i suggest you change it.

Hmm.. Okay that'll be my next upgrade. There aren't any stickers on it besides a warning label I assumed that they were taken off by the seller, is there anyway to check the quality software wise?

If there isn't any sticker or brand names on the power supply, i would probably want to swap it quickly. If you got from somewhere prebuilt, ask them.
You can check the quality of the power supply by measuring the rails with a multimeter that will determine the quality to an extent
