poor optimization for laptop GPU, excellent on desktop

(cuteYew) #1

Hello, first of all I would like to say that this is a most excellent free to play game and I would highly recommend it to anyone looking for something new to play. Any ways, back on topic. The main issue I have encountered so far with my 30 hours of gampeplay is poor optimization between this game and bitdefender (must disable everything for it to work as intended) and the difference in performance between my integrated GPU on my laptop and the dedicated graphics card I have for my desktop.

Both my PC’s are capible gaming PC’s, sure it is a no brainer that the desktop would have superior performance, but it still blows me away as to the awful performance I am getting with my laptop. Here are the specs:

GTX 860M GPU
intel i7 -4720HQ @ 2.6 GHZ
12 GB of RAM
Windows 8.1

Regardless to what graphics quality, settings or resolution I set it too, I always get the same choppy result. I can set it to look like runescape and still have major stuttering issues.

My specs are definitely above the standard for the recommended requirements, yet I get less that 30 FPS. Meanwhile on my desktop, where I do majority of my gaming, it runs buttery smooth, only occasionally do I get an error where the game goes into a black screen where everything freezes and I need to reboot my PC to get it working again. I understand that the game is in early access and patches like these require a lot of time, I am willing to be patient. I just hope that these issues can be fixed in the near future so that when I want to play this with a friend who swings by, one of us won’t get stuck with the almost unplayable system. I look forward to hearing a response and I’m curious to see if anyone else is experiencing a similar issue between laptop and desktop GPU’s.

Ignoring the obvious laptop is terrible for gaming argument, have you considered overheating? That’s the only thing I can think of, aside from obvious performance issues on a laptop regardless.

i would guess that db is using built in graphics and not the gtx i think there is a setting for this in the drivers somewhere but i havent owned a nvidia card in ages so i dont know for sure

I think we’re all ignoring the really obvious problem here. 2.6GHz.

Seriously, people are over clocking to almost double that to get a good frame rate. How can you expect to get anywhere close to decent with that.

The minimum requirements aren’t applicable in this case if you want GOOD frame rate. It’ll play on that sure, but it’s gonna suck.

OPs CPU is more than adequate for Dirty Bomb unless it is overheating or being throttled down due to energy saving settings.

Running a AMD Phenom 9850 2,5 GHz and a Radeon HD 6850 here. Getting between 30 - 90FPS (200 - 300 in lobby) on a custom settings between medium and high. I have to reject the clockspeed theory :wink: .

But to be honest there are a few things. One mobile GPUs are usually the lowest tier GPUs further limited, to get to lower power/heat. Same goes for CPUs. Also they usually have to share a fair bit more of the RAM. And depending on the powersettings might get limited further.

The fact that OP has the same problems irregardless of settings indicates a bottleneck outside of those effects. Could be anything CPU, Memory, GPU, Motherboard, Soundchip…
Could be as simple as the GPU not capable of rendering the resolution fast enough (no matter what).

Ofcourse optimizing plays a part in this. Other games might have fallback routines enabled that DB hasn’t so far, forcing the subpar laptop hardware, to do stuff it simply can’t.

(Ghosthree3) #7

You get trash FPS so you reject the theory? Ok.

Very possible, throttling isn’t uncommon, I’ve had a desktop cpu throttle by default until a motherboard setting was changed. It’s also possible that it’s slowing down from heat, it is a laptop.

EDIT: Also note that OP said that he gets the same low fps regardless of his graphics settings. This means it is NOT a gpu issue and something else is choking him. I’d put money on the CPU.

So you are getting 30fps (minimum)y and think this is ok… hmm well.
But there are enough people wanting stable 144fps+.

@OT:

  • Game can’t use more than 4 threads, so your i7-ht doesn’t help there.
  • The gpu quite sure won’t be the bottleneck. However, it is most likely connectet to the same cooler as you cpu.
    So as one stated above, I’d try to find out, if my cpu’s turbo is really functioning up to the 3.4Ghz (4 cores used), or if is beeing throttled because of to high temperatures.

To check this cuteYew should run msi afterburner in the background and play a match, tab out after and check the graphs are are showing use of the dedicated graphics card, rather than the intel integrated graphics. it’d be even easier if you could hook up a 2nd monitor and have MSI run on that while you play :wink:

Check the core clock for any fluctuations and match it to the gpu temperature to see if it’s overheating and thermal throttling, I’m not sure exactly but anything above 90 and you’ll probably see thermal throttling.

I haven’t used MSI Afterburner on a laptop before but I’m sure you can check between connected gpu’s to check to see if dirty bomb is actually using the integrated graphics.

Hm, this is something I didn’t consider. I’d expect it to be a bios setting though.

I don’t know how on earth that situation could arise though.

(D'@athi) #11

I found this one http://www.hwinfo.com/ to be quite nice, with probably all the info you need availible.

Switching GPUs between integrated Intel and discrete nVidia is a few years old at this point. It isn’t 100% reliable (but miles better than AMD’s version).

@Ghosthree3 @D’@athi kinda missed the point.

OP is complaining, that his laptop can’t reach 30 FPS regardless of settings.
Ghosthree3 suggested, thats because of the 2.65GHz clockspeed.
I only pointed out, thats not the problem. Because my aging desktop setup running at a slightly lower clockspeed (not to mention having lower RAM aswell), has no problem surpassing the 30 FPS barrier on higher than medium settings.

Meaning that the cultrip is more likely somewhere else.

Could very well be that the mobile GPU is not engaged (as people suggest) or that it has many processing units disabled to ensure it runs cool that it just can’t compute the workload (compared to a desktop equivalent). Can simply be that UE3 or atleast DB just doesn’t play nice with his mobile platform.

PS. I’m well aware that my aging setup can’t produce the magical 144. But on the other hand I got a matching 60Hz monitor, so I have no use for 144 anyways. And instead of having to resort to potato configs, in the hunt for more FPS. I can enjoy high world settings, player shadows, shiny metal surfaces and most importantly lightshafts.

(D'@athi) #14

Ok sorry, understood it wrong then.
Still wouldn’t directly compare clockspeeds between cpu-architectures.

(Mescman) #15

I have 765M, 4700MQ, 16gb ram and I can get a steady 100fps on my laptop, maybe even more? Haven’t tried. (With potato configs)

There’s something wrong with your laptop!

like @greatFactory mentioned earlier, I bet the problem is that DB insists on using your integrated graphics instead of your 860M.

(Ghosthree3) #16

Wouldn’t hurt to turn off HT to keep the heat down either tbh, even if it is the integrated graphics that are the problem.

(Mescman) #17

These days actually the only thing holding laptops possibly behind, is the overheating. Just the fact that it’s a laptop doesn’t automatically make it bad performance wise. Years back it was a different story.

(attentiveMonth) #18

I just had to jump in here due to the blatant megahertz myth.
Basically if you think clock rate matters read this

(Ghosthree3) #19

There is no doubt that Hz isn’t the only factor when considering CPU performance. But as we know that OP’s CPU is pretty damn new - 6 months old - the clock speed is the most relevant piece of information.

However that particular CPU ‘turbos’ to 3.6 from 2.6 so if it is in fact speeding up as it should it is not a huge issue unless heating is involved. OP stated 2.6 though so I assumed that was the highest it was going or he would have said 3.6.

(MTLMortis) #20

One other thing to check is to make sure that cpu core parking is off.
