Dotaz: nvidia a 2D vykon

[bman]

Ahojte,

 

presiel som z integrovanej dosky s Geforce 7150 na Geforce 9300 (rovnako IGP) a vykon v 2D je tragicky. Prekreslovanie obrazovky, okien, prehravanie flash videa. Toto bude asi vseobecny problem 8xxx-9xxx rady Geforce. Ale spytam sa, existuje nejaky sposob ako by som z toho mohol dostat normalny 2D vykon? (compiz nechcem, tam okna prekresluje ako tak, ale stale je to nic moc).

 

rovnake vysledky pozorujem na Ubuntu 8.10 s distribucnymi driverami aj s najnovsimi 180.27 (to budu nejake bety) pod gentoo.

 

zatial som nuteny ostat pri ATI HD3850 a fglrx, tam to ide celkom fajn, ale nechcem externe riesenie...

 

poradite?

Ja mam GeForce 8600m GT. Mam ty same ovladace, co ty a vse bezi normalne.

U tebe si myslim, ze by to mohlo byt budto primo Flashem. Otestuj vykon bez spusteneho flashe a kukni na zombie procesy.

Odinstaluj  program v86d.... me delal velke problemy.

Taky muze chybet knihovna...ten ovladac nainstaluj a odinstaluj. Zkus taky posledni stabilni verzi a kasli na betu .Podivej se na procesy, jestli tam neco nedela neplechu.Zdar a silu

ale toto robia aj stabilne drivre z ubuntu aj bety z gentaa. vo flashi problem vseobecne nie je. robi to aj ked minimalizujem prazdne okno z firefoxu kde nie je ziaden flash. podozrivo vela CPU zerie proces X. ale ono aby som bol presny nie je to nejake fatalne, clovek ktory nepresiel od lepsieho k horsiemu rozdiel nespozna.

 

podla Google je to celkom bezny problem pri 8xxx/9xxx kartach (co sedi, moja stara 7150 tymto netrpela):

 

• Horrible 2D performance in Linux with the nVidia drivers. 169, 173 and 177 drivers are all faulty.
• Firefox scrolling/switching tabs performance is horrible.
• Resizing windows/moving windows/scrolling in windows is slow/laggy.
• KDE4 is almost unusably slow.
• Xrender performance is horrible.
• Compiz Fusion very choppy, laggy minimize/maximize.
• KDE4/QT4 apps especially are very laggy and unresponsive. Example: button press, dragging/resizing windows, combo boxes, menus are all slow.

 

vacsina symptomov sedi, a nestava sa to len mne, preto sa pytam ci to pozorujete :(

 

v86d nepouzivam...

tak som sa zacital trocha do for a nejake urivky:

 

I'm beginning to be totally fed up with GeForce 9300 / 730i mGPU on Asus P5N7A-VM. 2D is still slow with 180.22 but the worst issue is dual head related slowness. E.g. scrolling in Firefox in one screen while watching TV or video on other screen causes the latter one to halt to grind. I'm getting a second hand 7600GT PCI-E card since 7300GT on my previous setup was fine.

 

Wow! Just installed the Asus 7600GT into my P5N7A-VM, disabled the mGPU from BIOS and suddenly _all_ performance problems are gone! 2D is super fast. No tearing. Full screen flash is smooth as hell. TV/video running full screen on screen 1 plays smoothly no matter what I do on screen 0.

 

takze asi len cakat dokym sa nvidii uraci vydat normalne ovladace...
