Frame Rate Issues/GPU Utilization Jan 22, 2015 4:51:54 GMT

Post by r9delta on Jan 22, 2015 4:51:54 GMT

Operating System: Windows 7
Relevant System Specs:
Intel Core-i5 3570k 3.4ghz (3.8ghz Turbo Boost) - Not Currently Overclocked
8GB DDR3 Ram
Current Resolution: 1920x1080 (although results are almost the same at any)
GPU: Nvidia GTX 980 (not being overclocked)
GPU Driver Version: 347.09 (Latest stable)

Besiege Version: Alpha v0.01 (Windows) (latest off of Humblebundle.com as of 1/21/15)

Description of issue: I'm having some what i'd consider major frame rate issues with this game, most of the time when there's nothing going on the game will run at 60+ FPS when there's nothing going on, or very little with only a simple machine built but anything more complex will tank the frame rate commonly into the teens. I've ran a program called MSI Afterburner to monitor temperatures and utilization and it seems that my GPU is not being utilized at all. Utilization will be anywhere from 1% to at most 5% where as any other modern game I run will be 30-40%+. The CPU seems to be utilized around 40% as well regardless of what's going on (not sure if that's indicative of the issue or not). This is consistent no matter what resolution i have set, windowed mode or fullscreen, or any amount of graphical details I do or do not have on. This is easily reproduced, at least for me but seeing as no one else has reported this issue i'm wondering if it might just me unique to myself.

A good example of this issue, at least on my computer, is shown by playing Zone 5 using a machine like this one: besiege.freeforums.net/thread/59/tank-armed-quad-cannons-flamethrower

Again that said, I don't know if anyone else is having this particular issue but my system specs should definitely be up to snuff for this game if not overkill. Anyway beyond this issue for me, I love this game and can't wait to see more of it

Because every object in Besiege is physics based creating massive machines or machines with loose/wobbling parts can severely harm the performance of the game. Obviously this is only the first alpha build and there are probably more performance tweaks that can be made as development proceeds, to help in the short time, with large and complex machines, slowing down time can significantly increase your frame rate.

The Machine that you have linked has more than 300 parts that make it up and contains a large amount of moving parts. That being said, as the author recommends, if you slow down to 60-80% of norm you should get a steady framerate.

I'm in an even worse situation. I have similar specs as the op, and the game is a completely unplayable 10-15 fps for me. I hope the game is better optimized in the next build, as i would love to actually play it!

Are you using machines such as the one that Delta posted or are you saying you get a low framerate with any machine?

Thanks, yeah it's totally understandable given the game is still very early. It's mostly the (lack of) GPU utilization that bothered me (although I imagine this would mostly be a CPU bound game anyway) and I haven't seen anyone else report this kind of issue so it was also to gauge if this is just unique to my computer or if anyone else is encountering this. The frame rate does drop down below 60 for even rather simple machines sometimes but it's less severe compared to the one I linked. Anyway I'm sure there will be a lot of optimization done further down the line and I appreciate the response.

I'm a fricking moron. I recently changed my os, and forgot to reinstall the drivers for my graphics card. That having been done, the game runs quite well, and was alot of fun.
Sorry for the inconvenience!

I am also having frame rate issues and lack of GPU utilization.

I did get a little carried away with my building however I am only about 1/3 finished. I seem to have run out of resources a bit early (I am still limited to the cube also), effectively limiting my creativity significantly.

I think the explanation above makes sense. I hope there can be a LOT more optimization done (and direct more of the calculations to the GPU vice CPU) to expand the creativity primarily, but of course to address the performance also.

I look forward to finishing my franken-chine

PS. I specifically used a LOT of "braces". They seem to be the culprit of the huge performance hit.

Thank you

We are of course constantly looking at ways we can improve performance.

I suspect the most gains (and perhaps also the most work) would come from coding the physics to tap into the enormous power the GPU. CPUs today still have a hard time with physics. I would suggest looking at OPENCL to offload the CPU which could make for some really expansive scenarios and it compatible with both NVIDIA and AMD solutions.

Thank you
