ไม่หรอกครับ เหมือนเห็นว่าซัพพอร์ทมันตั้งแต่ series 5000
At CES, various display makers exhibited their gaming-grade monitors featuring NVIDIA G-Sync, a display fluidity technology that's an evolution of V-sync, which we've seen with our own eyes to make a tangible difference. AMD, at the back-room of its CES booth, demoed what various sources are calling...
อ่านดูในนี้เห็นว่าภาระตกไปอยู่ที่ GPU เหมือนเดิม(อีกฝั่งไปอยู่บนชิปเพิ่มในจอ) เห็นว่าเป็น VESA standard เกี่ยวกับ VBLANK อะไรสักอย่าง
จอต้องซัพพอร์ท Variable VBLANK ใครพอจะรู้เรื่องมันก็อธิบายให้ฟังหน่อยก็จะขอบพระคุณมาก

VBLANK is the time difference between the last line of one frame and the beginning of the first line of the next frame.
During the VBLANK the incoming data stream is not displayed on the screen - wiki
Originally posted by TechpowerupIn AMD's implementation, VBLANK length (interval between two refresh cycles where the GPU isn't putting out "new" frames, a sort of placebo frames) is variable, and the driver has to speculate what VBLANK length to set for the next frame; whereas, in NVIDIA's implementation, the display holds onto a VBLANK until the next frame is received. In NVIDIA's implementation, the GPU sends out whatever frame-rate the hardware can manage, while the monitor handles the "sync" part. In AMD's the speculation involved in setting the right VBLANK length for the next frame could cause some software overhead for the host system. That overhead is transferred to the display in NVIDIA's implementation.Last edited by mathburn; 7 Jan 2014, 21:19:38.
