Salve a tutti.

Dispongo di una scheda video Nvidia GeForce GTX-460 con 2gb di memoria, per il mio hackintosh (Niresh, Mountain Lion 10.8.4).
Ho installato i driver CUDA, i driver nvidia ed ho effettivamente l'accelerazione video, ho provato l'app "Chess" e mi fa fare delle mosse, quindi, deduco ci sia.
Le animazioni sono tutte molto fluide (non posso dire lo stesso delle registrazioni).
Riesco a vedere video su youtube, l'unico problema lo risconto quando gioco.
In pratica, prendendo qualche app di FPS (Red Crucible 2) dall'app store, noto che se per esempio osservo un muro e poi mi giro, il bordo del muro non va "a tempo" (magari la parte sopra del muro è qualche pixel sfalzata dalla parte sotto, come se il muro si dividesse in due).
In base ai giochi il problema può essere più o meno accentuato.
Consigli per vedere se effettivamente QE/CI è attivo? Vorrei riuscire a sfruttare appieno la mia scheda video, purtroppo così è un pò brutto giocare :(

Premessa, ieri dopo aver letto questa guida ho smanettato e ho fatto danno, quindi ora sto cercando di tornare al punto in cui ero prima di far danno, visto che ora va tutto a scatti ed è un macello.

Rispondendo alla tua domanda, al momento no, ma prima di far danno sì, la barra di stato era trasparente, aggiungo, magari serve saperlo, che i video si vedevano bene, registrava senza scatti (in qualità media, in qualità alta andava a scatti), sebbene con questo problema che qualche linea di pixel rimaneva indietro riuscivo anche a giocare, le animazioni erano fluide, gli screensaver funzionavano e non avevo alcun problema (videogiochi esclusi).

Sono riuscito a far ripartire alla perfezione il mac con tutte le accelerazioni video attive, ma il problema rimane nei videogame. Consigli? Sembra che sia dovuto al fatto che su osx non vengono sfruttare le OpenGL 4.4, possibile?

Spero vada bene questo test, se non dovesse andare bene indicatemi pure un test differente:
