(Sarcastic) Multithread support #1388

Closed Ameno-Sagiri closed 10 years ago

Ameno-Sagiri commented 10 years ago

With all this new technology coming out these days, I was thinking that FIXING the ability to utilize that brand new multi-techno-core and multi-tasking thingamajig that's appearing in the newest of games these days would really benefit people that use Garry's Mod for anything but Motion Blurring screenshots. 360fx360f

We're still waiting... GTX 670 used at 20% and only 1 core burning with a 2600K @ 4.6Ghz, quite frustrating...

Didn't you read what garry said?

A) Crashes - Hacks (A LOT OF HACKS) will need to be put in place to prevent weirdness from happening. B) Mutexes - Which will destroy any performance gain multithreading can provide.

UltimateByte commented 9 years ago

Then remove lua.

No, seriously, not everyone knows what mutex is, pardon my ignorance. Is that really undoable ? No fix possible ? Not possible to keep lua in one thread and the engine multithreaded ? Cause really, now when you charge gmod since a few years, performance level is just insanely low... User experience is shitty because of that when you try to make interesting things on beautiful maps, there's no other word.

What framerate do you get on gm_construct? What about with no addons?

UltimateByte commented 9 years ago

More than 150-200 with addons. But what's the point to playing gmod solo with no addons ? I'm talking of games in giant maps with hundred of props and more than 30 players...

notcake commented 9 years ago

And what fps do you get typically in that case?

UltimateByte commented 9 years ago

15 to 30... Gpu at 20%, cpu at 18%... I even saw a guy with an sli of 770gtx and a 5960x having trouble (must be misconfiguration from him but still) at 8fps on the same map than me. rp_rockford... Even on freespace in build mode, there are hardcore builders on my serv, i can easilly go below 30 fps when my screen displays too many props. And i have a still pretry damn good pc compared to others, that's what makes me even more sad for them...

rp_rockford

There's the problem. Maps like that aren't designed with performance in mind.

UltimateByte commented 9 years ago

I was sure of that answer. That's why i had to say it's also bad when you charge any sandbox game too...

thegrb93 commented 9 years ago

Doesn't matter. The map is consuming a huge chunk of processing with all of the unoptimized visleaf checking, collision checking, etc. Bsp isn't very good for open worlds. I could be wrong, but the fact of the matter is there won't be multithreading support. Try turning off shadows. That usually takes some load off of your cpu. I never go below 60 though with my i7 3.4ghz so not sure what's wrong with your 4.6ghz.

UltimateByte commented 9 years ago

With nothing on rockford and no addons i achieve 115 fps. With players i usually go under 20fps... And 20%gpu, this is the real issue. As i said, if ir was multithread, like capable of using 4 cores, i'd achieve 4 times the framerate...

By the way, one more time : even on flatgrass or gm_construct witj pretty epic builds, like trains designed with s-props with nice materials, online, i go under 30 fps easilly. Still with 1 full core and almost idle gpu. I guess I don't need to argue anymore as the issue is known and recognized. I just had to mention the critical framerate issues it caused. And i don't even talk about stuttering while spawning a new prop, or game freezing at launch while checking subscribed addons (not sure if that last one is multithread related), or loading time, or again freeze at server join when it jas lots of props... The point is you can't exploit and enjoy all the nice things of gmod with such a poor framerate, gaming experience is just blowed up.

thegrb93 commented 9 years ago

Are you on linux? That could be another reason why. Try turning of prop spawn effects and physgun halos to get rid of the stuttering. I know someone who had that problem and he uses linux. OpenGL seems to run slower for Gmod and Dota2 last time I tried. I use windows and don't have those problems.
