c++20 gonna be liiiiit

Lit like a dumpster fire

Don't be like that, c++20 is bringing some great features

It is, yeah

header files, fuck header files

Modules, concepts, std::format are more than enough for me

❤️

is tw cpu or gpu "bottlenecked"?

15:11

okay after quickly testing it's cpu bottlenecked for a single core

try gfx_finish 0

15:15

but at least if you have a dedicated gpu it's really limited by the cpu

15:15

mostly because it uploads all vertex data to the gpu each frame

15:17

by storing the text and map data on the gpu you can easily get ~90% gpu utilization while keeping the cpu load kinda low

what does this command do? I have not quite but close to doubled my fps with it

15:20

it's still "just" 70-80% gpu utilization but much closer at least

gfx_finish 1 makes sure that the gpu finished rendering the last frame before submitting commands for the new frame in certain scenarios this can reduce input latency, but most of the time it just wastes gpu performance, since the gpu is idling while the cpu is preparing the new frame

15:42

in tw it usually does not matter. for me the game runs with >1000 fps anyway

@redix I think you kinda broke net_addr_comp, it no longer returns the correct order

what order?

Atleast the comment in system.h needs to be updated it never returns >0 anymore

16:57

If something like a sorted array of NETADDRs was relying on net_addr_comp > 0 to order it, it would have broken

yeah okay. but i'd rather just change the docs

Sure, but that won't leave any way to have an order relationship between NETADDRs just so you know

true, but one can add this if it's really needed

17:15

since we have prediction for other players now... what about projectiles? no real physics prediction, but rather just displaying them at the position for the predicted tick, so all objects on the screen are in sync

17:16

for high ping the projectiles may seem to spawn late and fly through walls then, but the experience with prediction for other players is also awful with high ping

17:17

just as a note: that would only require changing a few lines

yeah, sure sounds good

17:23

but should probably make a config for it, so people can turn it off. just in case

yeah sure, it should also be disabled by default, like cl_predict_players

yeah

@Dune if oy appears again, I started a versionsrv running on current master (2020-09-05, dccfaf9354af1dcfbdf60fc517f669346aa8b578) on version.teeworlds.com

good thx, anyone tested if it works?

@heinrich5991

17:28

iirc it doesn't

hm ok, maybe it's the server?

17:30

can't reproduce it and don't see any changes that could cause that

redix said "but still no response ="

17:44

yeah henrich5991.de works so it's the server somehow

Anyone ever experienced the problem that you can see all servers in the browser, but cannot connect to any? After restarting the game everything is fine =\

17:48

Maybe some uninitialized stuff...

Cannot connect as in stuck on the connecting screen?

yeah. times out after a few seconds

Next time it happens, launch wireshark

yeah should do that ^^

17:49

experienced it several times, but it's kinda seldom

It happened to me once or twice before, but I chalked it up to the very broken 0.7 bridge stuff I was messing around with
