Seeing bottlenecking in battlefront 2, wondering if its my processor

Getting considerable buffering, lag, and frame dips on Star Wars battlefront 2

my rig:

ryzen 3 2200g overclocked to a stable 3.8 Ghz (watercooled)

2x4 ddr4 ram overclocked to a stable 2993 Mhz (from 2400 Mhz)

msi b350 tomahawk motherboard

gigabyte gtx 1060 windforce OC edition running on OC mode (1798 Mhz boost, 8008 mem boost)

1TB HD

400W PSU



fps stays above 60 but with buffering and lag. sometimes i even get frame dips that go to low 50's. 1060s usually hit high 80's on battlefront 2 and very rarely dip below 75 but thats on 4 core cpu rigs like i7's.

OH, by the way these numbers are on ultra setting's at 1080p (my fps and typical 1060 fps)



my guess is the limitations of the APU but I had thought that the overclock would give it just a bit more power. temps arent an issue either especially with it being liquid cooled. planning on upgrading to a 2700x soon but wanted to know if it could be anything else. if it means anything. my SoC voltage is 1.1 changed from 1.06 (just to give it a bit more juice) and my ram voltage is 1.350 volts.

PSU?
My rule of thumb is to aim for about 60% load to minimize fan noise and leave room for both expansion and power SPIKES above the average.

It appears 250W is roughly what you might draw (max, but hard to be specific with variability of coolers, overclocking, DDR4 memory etc) with an R7-2700 + GTX1060 but while 450W should be fine it's not much money to go a little higher anyway which also places less stress on the PSU components.

THIS model has an ECO MODE which should turn the fan off below 50% load (275W) so it might be a good choice to minimize noise:

SEASONIC does not have the same cutoff so do your research. May vary by model too. Example...

With all that overclocking, I'm surprised that you only have a 400 watt PSU. May I ask what brand and model it is?

Sure its an evga 400W PSU. here's a link to view any details you may want to know:

According to this:
https://linustechtips.com/main/topic/631048-psu-tier-list-updated/
That particular PSU resides in tier 7, the worst. I am surprised that your PC works at all, especially since it is overclocked. IMHO I suspect that the PSU is not the most stable, and that may be causing your lags and frame dips.

YIKES!! thanks for the heads up! I'll get that replaced immediately! tho I suspect it might not be the psu causing my lag and frame dips since i hit my monitors refresh rate cap [75 htz] consistently in games like fortnite. its the more graphically demanding (and i suspect CPU demanding) titles that it struggles to keep solid frames in but I dont claim to be an expert in any regard so i will definitely take your word on this one. Also, would the PSU be a possible cause for the inconsistent boot up and shut down times i experience as well?

Anything that could cause a component to instantaneously draw more power, for whatever reason, could be affected by an unstable PSU. Usually, this would cause crashes and re-boots. It may be right on the threshold of these crashes, not actually crashing, but still causing intermittent problems.

Ok! should i take any precautions now (setting my cpu to stock frequency, ram to stock frequency etc.)? I've had the pc for a little over 2 months now. ive upgraded it incrementally throughout that time. would any of the parts have experienced damage during that time due to the PSU?

Skip down to the bottom. (take that for what you will, but I consider a PSU an investment.. it's not just the ability to deliver the power which actually SHOULD NOT BE AN ISSUE for it and your build but also OVERCURRENT PROTECTION which is probably quite limited).

Picture links don't work but you should get the idea just from the conclusion.

*It's not impossible the PSU is the issue but I'd suspect it's your CPU. I'll look further though.

thanks for the tip. I had thought that it was my cpu as well but im not one to shrug off advice when its given to me especially when it comes to fields im not particularly an expert on.

Planning on upgrading to a 2700x next week. should i consider getting a 450W or 500W modular to couple the processor [side note: my rig (with the 2700x) will never expeed a 450W power draw]

Just after 3 minutes you see the CPU is totally maxed out. I can't be certain that's your problem but it may be. You may want to invest in an R5-2600 at some point. (update: okay, saw the R7-2700 comment)

Also, not sure if that's a 3GB model or 6GB GTX1060 but if it's a 3GB model you may be hitting a VRAM limitation.

*Sudden big drops are often memory related but hard to say.

**You should also drop the game SETTINGS down a lot to see if things become smoother.


Summary:
Hard to say exactly where the issue is but again you seem to be maxing out the CPU, possibly VRAM (if only 3GB), and yes I'd replace that PSU with a quality one of 550W or so.

Ok thanks for your advice! sorry I wasn't clear on the amount of ram the gpu had but its 6gb. here's the spec sheet in case the gpu might be the issue but i agree with you with it most likely being the cpu: [https://www.newegg.com/Product/Product.aspx?Item=N82E16814125881&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Video+Card+-+Nvidia-_-N82E16814125881&gclid=Cj0KCQjwzK_bBRDDARIsAFQF7zO143saI2mcqhrMHfDYm_e8FLIuRZlrMO7L1GDOC-m35qMSn--zX_8aAhZlEALw_wcB&gclsrc=aw.ds]

anyway thanks for the help!

Not sure but I think it cuts off at 30% but the fan should be pretty quiet above that. (fanless mode is button out I believe)

Lots of other choices too but trying to list a couple that are not too expensive but appear to be reliable and have fanless options too (some PSU's have noisy fans for some reason even in light usage).

Just FYI,
When you see the FPS reported fairly high but see big stutters or even small judders that does mean that you are dropping FRAMES.

Most people aren't aware that REPORTED FRAMES are not the same as CREATED FRAMES. Programs like FRAPS count a frame once it is REQUESTED but it's very, very common for a frame to never be created after that.

60FPS should be quite smooth. If it's not you are dropping frames. That's where FRAME TIME ANALYSIS (i.e. 0.1% and 1% lows) comes in.
