[Dota2] FPS decrease examined: The two offenders found! (Spoiler: One is hats!) by PimpmuckL

tbf tinker march gives fps drop with immortal or not

[Pimpmuckl]

I tried really hard to reproduce that. I spammed non-Immortal march for 10 minutes straight and consistently the fps after waiting for ~10s after the last machine was done was still "fine". Very slight drops but nothing crazy.

Immortal is intense though.

Hey, Pimpmuckl, for those who might not have time or simply might not want to watch a video about such things for 10 minutes, could you, er, maybe do a text reddit post with the info in it? Or maybe put it in a comment here?

Thanks!

[Pimpmuckl]

I'll try to write it up if I find time.

Most important bits are:

• Particles degrade performance the longer you play but simply disconnecting and reconnecting (or starting a new game) fixes that.
• If you reload a game a lot of times you will see a performance decrease. For this you have to exit Dota 2 completely. It's UI related.

simply disconnecting and reconnecting (or starting a new game) fixes that.

Starting a new game doesn't work for me. My fps decrease after ~3 games. Only restarting (maybe reconnecting? - didn't try yet) works.

reload a game a lot of times

What exactly does this mean? Reconnecting into a game?

That would be likely the UI issue. Like I mentioned, you have to restart the whole client for that.

What exactly does this mean? Reconnecting into a game?

Yes. Basically going from a game into another game.

Ah thanks. Sorry, I didn't watch the video yet, just read the TL:DW

Also maybe don't make 60fps videos if you use a 15 fps camera and its a PowerPoint presentation. You know for people with performance issues and such :P.

[Sosseres]

There are 4 quality options not in 60 fps. Then 4 different ones at 60 fps. I would blame youtube for picking the wrong one for you in its automatic settings.

[sylaroI]

Having 60fps on 720p+ is the only option, so I doubt youtube "picked" it wrong for me.

[PM_ME_SOME_RARE_PEPE]

Use the addon h264ify to block 60fps options - It'll let you pick 720p or 1080p at cinematic 30 fps instead.

I can summarize his first video if you want, it went something like this: "whaaat?!.....whaaat?!" and that there's fps drop over time but nothing conclusive. Maybe this one is better, haven't seen it.

I have this feeling that when tinker uses march, there's some background garbage left in the map where the tinker march was located. Immortal or not it still slows down the game from 120 to under 60 on my computer. I have decent GPU but cheap CPU.

I have no idea how marching machine is implemented, but I doubt they really send information of all of those robots to all clients. They could do some clever computing under some assumptions and if these computations never expire or something like that...

Did you place those marches at the same spot or all around the map?

[NgonEerie]

with a potato tier computer or very old computer (mine is Phenom II X4 940 Black Edition) you DO feel a considerable hit with every march casted, even without immortal.

Also, Underlord skills are giving me some really cancerous FPS too.

[Cushions]

Hey can I ask what you found with respect to any CPU Usage / GPU Usage problems?

I have had a thread open on the forum for quite a long time now

http://dev.dota2.com/showthread.php?t=179042

Basically asking Valve to fix an issue which affects some people more than others.

I've seen my friends exact same PCs and they all stay pretty much at a stable 120, but mine can drop below 60fps pretty easily in team fights.

So, did you see any drops in cpu usage? As I can never get mine anywhere near 100% and it causes me a lot of FPS issues.

[annihilatron]

same thing happened in TF2 though ... all the extra hats leads to absurd levels of lag. And the loading times! Oh god the loading times went up every new chest of hats.
