Nex 2.0 runs fine for me, but Gonzo has some weird problems with his display. after the loading screen finishes, there's this strange flickering on his display, like his monitor is running on 30 Hz, though an analysis proved its running on 75 Hz. its there all the time, in the menu and ingame.
is this a known problem and does anyone have a solution ?
his specs are:

P4 3.0 / Gf FX 5900 / 1 Gig RAM

cheers

OS and driver info might be helpful, too.

Does changing vid_refresh on the console help?
e.g.: vid_refresh 75; vid_restart

ups, sry
he's running nex on winxp with the latest official nvidia forceware (84.21)
had the same idea with vid_refresh but it sadly had no effect

Also please mention if he uses dual monitor. Maybe this information will help. There once has been a bug when using two monitors running windows, that one should be fixed but one can never be too sure . Only using one monitor (disabling the other in the system settings) might help then.

I use the same driver with a Geforce 6600. No problems at all.

I remember about years ago when my company's CAM Application changed the resolution automatically, there were cheaper Displays who began flickering and making scary noises. Disappeared after a few seconds. Better models didn't show reactions like that.

What about using windowed mode?

Ah, color depth both Nexuiz and OS set to 32'?

If he is indeed running a dual+ monitor display, just disabling hardward gamma in the menu may fix the issue.

just asked him. he's definitely not using dual-display and i dont think its the color depth. going to try some more stuff at his place tonight, so if anyone has some ideas about what to try, any suggestions would be welcome

While he might not be using dual monitors, it might be set so in the nvidia manu.
I had this issue a long time ago. Check that just for shits and giggles.

*problem solved*

sometimes the easiest solutions are the right ones
made us laugh for 30 minutes

What exactly was it? The nVidia menu?

yep

I got the same problem on my dual scren windowsXP running nexuiz wondowed. Disabling HW gamma fixed it, however this was not a problem with the forum release of 2.0, but it appeared in the final release

A64 3200+ GF 6600

The forum beta had a bug that caused it to not set gamma on startup sometimes, which I fixed, but in a way that I was convinced would not cause the infamous 'flicker', how is this still possible?

You asking me? Let me know what you want me to test

btw: I never had this issue in earlier versions.

Good thing i still have that windows partition.. so if i find some time tomorrow i'll try to test this on windows dual monitor mode.

I have the same weird flickering, but I'd say its for different reasons. It only does the crazy slow flicker when I'm running Dualview. XP, GB ram, 6800GT. Refresh rates are 65 on left and 75 on right screen.

So I turn off dualview and go to single dislpay to play. One other note, I'm also running 84.21.

Edit: Just saw the posts about HWG. Turning off the hardware gamma fixed it.

Daeduls ... there is a way to make your own montitor drivers (iitc Ntweak allows it do do (don't recall the name for sure though)) This file will generate a montitor driver file that only allows your screen to work at it's maximum frequencys... Could be interesting, with that "fix" you will never have to worry about refreshrate again.... ever ...

Could not yet test it but i suppose the flickering was fixed with a engine change 4 hours ago. Should be included in the next bug fix release 2.0.1 (or something similar)

I'm doubtful that fixes it, I need someone to test it and report back.

Someone provide a win compile and I'll test

tried it with strange results.

hw gamma makes the screen(s) flicker unless color control is on

if color control is on brightness/contrast dosent work (but color sliders do)

with both color control and gamma on the screen sometimes flickers dependning on how i set the color sliders and some positions on the gamma slider seems to trigger it too.

both off and it dosent flicker as far as i can tell.

system info:
amd a64 2800 / 1gb ram
gf6600gt
one dvi tft, one crt screen
windows xp pro sp2
uppdated drivers and bioses

That's standard behavior - color control is an alternative method of setting things.

Again normal cases for it to not flicker.

Thanks for testing that, it was just a simple bugfix for something to do with the v_psycho easteregg, I was only wondering if it was involved in the flickering bug, evidently it is not.

No further testing needed until my next guess at the bug.

I'm pretty sure I've fixed the gamma flicker bug now.

It does not flicker for me when using dual monitors in windows. But i think it does not change gamma at all. Can't test it better right now though. Might be able to later the day when i'm back home..

Tested.
Screen flickering gone for me now. so I can now run with HW gamma. My fix was to turn HW gamma off. It used to flicker with HW gamma on.

Sysinfo:
Asus A8V Deluxe
Athlon64 3000+
Asus G6600 (NVidea 6600) with old drivers
WinXP SP2

I had a dual display monitor and noticed the flickiering problem too...running Windows XP. A simple solution for me was just to run in single monitor mode.

Much simpler is to disable v_hwgamma. That is no longer needed with an uptodate engine. I'm not sure if Nexuiz 2.0 already has a new enough engine but the upcomming 2.0.1 patch will for sure. As v_hwgamma will then no longer work on dualmonitor you can use r_hdr_scenebrightness to make things brighter. A value of 2 seems to work quite well.

r_hdr_scenebrightness works, yes it looks nicer too but (at least for me) it does provide less visibility then gamma. i frquently have problems with nos seeing players untill its to late (specialy the gray, some yellow and brown skins) when i cant use gamma. thats kinda enoying. Acctualy player vs world contrast has gotten worse with the new skins imo.

I think you are right, i perfer v_gamma as players are more visible then. At least it seems so to me too .
I would love to get my hands on CSQC in DP to allow forced models/skins to make things more visible.
