Sli Support Improvements; Display Driver - Nvidia Quadro Workstation User Manual

Chapter 1
Introduction

SLI Support Improvements

• SLI support for OpenGL workstation applications with Quadro‐based PCI‐
Express graphics cards.
• Additional SLI support — Release 75 adds support for the following combinations
of PCI Express graphics cards and NVIDIA products, as listed below:
NVIDIA Product
NVIDIA nForce4 SLI
NVIDIA nForce Professional 2200
NVIDIA nForce Professional 2200
+ NVIDIA nForce Professional
2050
All NVIDIA GPUs
• Improved SLI performance for DirectX and OpenGL applications
• Improved end‐user control of SLI profiles and rendering modes – see descriptions
of SLI‐based options in "Adjusting Performance and Quality Settings" on page

Display Driver

• Improved support for custom timings, including non‐divisible by 8 resolutions on
TMDS/LVDS panels, control of back‐end and front‐end timings, and variable
overscan shift values.
The driver can also present underscan modes on demand, and supports variable
underscan ratios.
• Off‐screen 2D memory management optimization
• Efficient synchronization between clients allows for sharing of off‐screen resources
with DirectX applications. This avoids potential performance issues with
applications that use DirectX rendered surfaces in ways that conflicted with 2D
caching.
• VESA Coordinated Video Timing (CVT) Support
Support via control panel option for analog monitors
•
• Support for CVT/CVT‐RB timing restriction using R&T strings
• Color compression support
• SLI Enhancements
• SLI screen capture support
