V Sync and Triple Buffering

[inf3rno]

Same issue here.

 

I havent fond a solution yet, I thought it is a mysterious network problem cause I felt about 150 msec ping, instead of 50 ping I had... So I changed every network devices (except the modem), but nothing helped...

 

Then I realized the r_swapimages (vsync) and r_finish (options / sync every frame) changes a lot in mouse movement - audio - video - hitbox synchronization, so I turned them off. Now I think I have the delay only in the video. I can hear people shooting on me, but the monitor displays the hits and everything later.

 

It can be still network problem, because sometimes I have 999 ping until 5-10 seconds in every hour. So something is definitely not ok with my pc... :S

 

For example: I played against a 200ping player, gave him about 2 hs, then he went behind the wall. After that I started to went back too (opposite direction), because I heared others coming... Then he started to push forward, and I heared the hitsounds, but he wasnt displayed on the monitor, just a sec later after I heared my medic scream so after I really died... Sometimes I hear them shoot rifle nade, I jump, but die, because it blows up about a sec earlier. But if I shoot a rifle nade or drop a simple nade, it blows up a sec later... I cant kill ppl corner camping or cant kill anyone while I am jumping, cause nothing hits from close range, hitboxes aren't sync with the display.... :S Sometimes when I go into a room it seems to be empty, but after half sec ppl appear there I had funny situations with that, I looked into a room for just a wink, it was clear, I started to turn around, but 3 enemy appeared from nothing... Sometimes it's sync with the sound, sometimes not. It's hard to find out, because I can hear ppl behind the wall, but I can't see them...

 

The stranges thing I had the 5-10 sec duration 999ping, cause I can see what happens on the server, but I cant move. If I freeze what 2 click nade in my hands I doesn't blow up, just simply drop the nade after 10 secs... I have the same with TS, I can hear ppl, but I cant answer... So maybe the network upload / download is not in synchrone, or something like that... So technically I can't upload for 10 secs, but I can download, and the server does not kill me with nade in my hand, it waits until my upload comes back... Never seen something like that before...

 

Any idea how to fix this shit?

 

Ohh I have

• intel core2duo E8400
• gigabyte geforce gt 240
• gigabyte ep43t-usb3
• logitech g400
• dell u2312hm
• kingston 1600mhz 4gb ram (I run them on 1333mhz, the cpu is default on that)

why this line?

 

 

seta r_lastValidRenderer

 

Even if your ping is 500 or higher, you should still see everything matching with the sounds you hear (of course not hitsounds, for obvious reasons)

 

But all the sounds when you shoot, when enemies shoot, etc. should be in sync with the video. Make sure you don't have vsync enabled, or other settings which could cause a delay between what you see and what you hear (I don't mean in your game config, I mean in your graphics card settings)

 

And set r_swapinterval to 0 (but you have it already), r_ext_swapinterval doesn't exist in Enemy Territory

 

edit:

p.s.

don't revive such old threads, especially if your issue isn't necessarily related

I think this was an rtcw config, my friend gave it to me in 2003... I made only small modifications in it, so I don't know what is r_lastValidRenderer for...

it should be the name of your graphics card, but you're not supposed to set it yourself

 

anyway, if you enter a room and it's empty then you suddenly see players inside, that's lag on your side.

 

How many frames per second do you usually get?

[PiNoY]

could you also post your winmtr results, to see if there's any packet loss at your end or your ISP as well.

[Glyphz]

seta rate "80000" ?   

[SunLight]

As regards sounds, the sounds are played according to what comes from the server (hitsounds, other players shooting, explosions, etc.) and what your own client simualtes locally (I think this is the case for the sounds when you shoot yourself).

 

Hitsounds of course have a delay, but other sounds like a grenade explosion, should be in sync with what you see. If not, then it can't be a network problem, but it must be a delay in the graphics driver/monitor 'chain', you can disable vsync in ET, but your graphics card settings might override that.

I had an lcd tv with 100msec input lag, and this is not the same. With input lag the map and ppl are both displayed on the screen a bit later. By this, the map is displayed in the right time, and just the ppl, nades, etc a bit later. So this is a deeper than a simple input lag, this happens before render, and I think it has to do something with network, but I don't have the proper skills to debug this...

 

Answer for several questions:

 

I have 125 fps. Could have 333, but the connection is not enough for that.

Vsync is disabled by graphic card. More accurate: I disabled: anisotropic filtering, antialiasing, texture filtering, threaded optimization, tripple buffering, vertical sync. Neither of them helped.

Rate 80000 is ok.

I don't know what "winmtr results" are.

[jaie]

can you post a demo of you lagging.

Do you get the same lag in other fps games?

winmtr results are the results of a traceroute between you and the server to see if there is any abnormal packetloss or delays along the way. (using the program winmtr)

[PiNoY]

might be interested to read more FA's tutorial on How to Recognize your Lag

 

http://fearless-assassins.com/tutorials/article/57-how-to-recognize-your-lag/

 

also,you can download winmtr software (32bit / 64bit) here, how to use winmtr is also mentioned here:

Then I think it's network lag. Actually, I don't know how you know that something is 'late' if you don't have a reference...

 

But take into account that in the game there are 2 simulations, one on the client, one on the server. Let's say you have a lot of lag, and you enter a room. In reality, maybe you aren't inside that room yet in the server, only in the client simulation.

When your lag stops your position is readjusted, and maybe some players will 'teleport' there. Personally I never had such hard lags, so I don't know how it would look like. Do you get 'connection interrupted' messages?

 

Maybe a screenshot of your lagometer could help, or even better a demo recorded when you lag.

[S3ti]

My config

 

I don't think it causes this massive lag, but your config is quite messed up. There are a bunch of cvars with the wrong syntax, are obsolete or don't even exist in ET. With that config you are running PB as client and a server e.g...delete it and try with stock settings.

Looks more like some connection/isp problem if you have same problems with other programs like TS, monitor it and do traceroutes and bandwidth tests.

 

Gamewise lower your rate to 25000-50000, try r_finish 1 (that's NOT vsync), check for rootkits and trojans with a few different programs.

Yes you are right, but as you said yourself that can't cause lag. Nonexisting cvars or server-side ones would just get ignored

 

For example rate is a maximum threshold, if you lower it nothing would happen.

 

rate 'x' is like telling the server: 'don't send me more than x', it's not necessarily reached

r_finish 1 feels like mouseaccel if I turn it on (was turned on for a while, better without that)...

I changed rate on last week from 25k to 80k, so rate is not the problem.

I have eset smart security, can you recommend a better antivir?

[SunLight]

I have eset smart security, can you recommend a better antivir?

I don't know, I use Linux and I have no antivirus, but I would suggest you this:

 

play always with /cg_drawfps 1 and /cg_lagometer 1

 

if you see your fps is high all the time, then it's not a cpu/antivirus/etc problem but a network one. anything using your cpu should cause a visible slowdown in fps, even if for an instant

 

if fps is ok but lagometer shows lag, then it's a network problem (or some other software downloading). Lag doesn't affect your fps
