Holy OMG wtf BBQ FPS???

[Forboding Angel]

I've been ripping apart SSMF maps all day trying to figure out why on some maps for no reason I get shit FPS. I have narrowed it down to the fact that _Nothing_ in SSMF causes me any slowdown.

But then, completely on accident I notice this...






Wait WUT??? The settings in both screenies are exactly the same. Nothing has changed. The screenies were taken seconds apart (look at the ingame timer).

Here are my settings:

What the Eff is going on??? O_O

In the second set of pictures you seem to have LOS in the first picture and no LOS in the second. Maybe LOS causes the slowdown ?

[Anarchid]

Maybe LOS causes the slowdown ?

Fails to explain the first set.

[Forboding Angel]

I changed nothing in any of the screenies. I went and checked. It is indeed LOS that is causing the drop. But for the love of god, why would los be causing a drop like that???

[malric]

Maybe because of HighResLos? From your config:

Code: Select all

HighResLos = 1

For the source code (https://github.com/spring/spring/blob/d ... er.cpp#L25)

Code: Select all

Controls whether LOS (\"L view\") edges are rendered in high resolution. Resource heavy!

holy moly LOL #swagmaster


hold your nuts for a moment, loko at my oversized embedded picture:

as you see i have 3 digit fps. u run shitrig? lol JK
hear a picture with los on the fps is almost same:

(i know some of u post from your iphone so i linked it!)

The settings in both screenies are exactly the same. Nothing has changed.

excvept f1 mode and los amirite mahlady?=

What the Eff is going on??? O_O

no advmapshading for me! makes fps like #pcmasterrace
probaly no detailtexturesplatmap nextgeneration in special f1 mode?
did u try witout? or resize splatmap? pls respond

It is indeed LOS that is causing the drop.

The first image-set you posted has two images, of which the first also has los off and ~30 fps. Either this contradicts your conclusion, or you have presented misleading data

[malric]

Also, by looking at the source I think the smaller ExtraTextureUpdateRate, the worse performance. Default is 45, yours is 4.

@Anarchid: the first image seems to have LOS also (look at the minimap below and right of the star)

[Anarchid]

It doesn't look like the los-view in second series, but maybe evo default los isn't that visible.

What i *can* see, though, is hilarious shadow of the Overseer, seemingly cast *through* the hill :0

ExtraTextureUpdateRate = 4
HighResLos = 1

I told you multiple times that those tags are very very very very performance heavy and I told you you must test with _BIG_ maps, to find out if your system is able to handle the setup. And still you did NOT do so, instead you blamed engine for a low fps!


PS: There were over weeks a discussion to increase default ExtraTextureUpdateRate, cause they found that it updates too slow for fighters and causes texture tearing. All those who know of that tag said over and over I should `simply` reduce it to 30 or even lower, cause their system was be able to handle it. BUT NO IT DOESN'T! THEY JUST TESTED SMALL MAPS! and ignored me over and over, till I ignored them.
SO PLEASE TRUST SOMEONE WHO KNOWS MORE OF IT, WHEN HE SAYS IT'S A BAD IDEA.

BumpWaterUseUniforms = 1

is wrong too. It's must only enabled for runtime changing of waterparams (there is a widget in toolbox for that, and the widget sets it itself and unsets it later on).

I heard repeatedly pressing F1 improves FPS, can you confirm?

i was one of those people.

intuitively the cost of LOS updates probably depends on RATE * MAP_SIDE_SIZE^2 * RESOLUTION^3.

if you reduce the resolution to half you should be able to multiply the rate by 4 or even 8 without increasing the cost for a given map.

Game config files can control the resolution, but they can't control the update rate.

The title of thread suggested free lunch.. im dissapointerd

...instead you blamed engine for a low fps!

No I didn't! What the fuck are you talking about? I was in #sy all day yesterday talking to you while I was trying to figure this out.

I have no been taking part in the springsettings thread, and I haven't really been reading it, so leave me out of any beeves you have with people in that thread.

I have continually asked you for advice, and you have continually been very helpful, and I am grateful for that. You also explained how ssmf texture compression affects gpu bandwidth and such, which was immensely helpful (you really should make a thread in the mapping forum about it).

I never once blamed the engine for low fps, and tbh I'm a bit offended that you make that accusation. There isn't anything wrong with the engine and I wasn't implying that there was. I spent 8 hours tearing down various ssmf maps yesterday in a learning exercise. It's not like I haven't put a shitload of effort into understanding how the engine works.


@everyone else...

The only thing that changed between those screenies was f1 being pressed.

[gajop]

I think what people are implying is that LOS isn't rendered (isn't updated either maybe?) in F1 and that causes the huge performance boost.

[Funkencool]

Out of curiosity, do you see the same change in fps when toggling just LOS?

[Forboding Angel]

Yep. JK was right, disabling highreslos was the culprit. I know I tested that when i enabled it. Apparently my testing was shit.

Lesson learned.
