In all my five years on SL, I've never had an issue graphics wise until I installed SL on my brand new rig. I have terrible graphics tearing, there's no blackouts between tearing....It's just a constant fast-paced flicker and only occurs on SL (When I don't have the game selected, or running behind another window the flickering ceases.) - no other games. This problem occurs for me across all viewers, including third party viewers (Firestorm) and LL's native mesh viewer. For reference, specs are as follows:- Power supply: Corsair TX750W Series V2 Enthusiast RAM: Kingston HyperX KHX1600C9D3X2K2/4GX 8 GB (2x4 GB) Graphics card: Asus ENGTX560 TI DCII TOP/2DI/1GD5 GeForce GTX 560 Ti CPU: Intel Core i5 2500K 3,3 GHz LGA1155 Processor Mobo: Asus P8P67 PRO B3 Intel P67 LGA1155 ATX Motherboard HDD: Seagate Barracuda 500 GB 7200 RPM SATA3 Currently I've tried D3DOverrider, a clean install of updated drivers in safe mode (Windows 7, ultimate 64x), tinkering with the enable vertical sync TRUE/FALSE option in the debug menu and messing with various Nvidia settings like disabling anti-aliasing/vsync in a custom profile for the viewer. I've also turned off VBO and anti-aliasing in the viewer preferences with no avail. Can anyone shed any light on the issues I'm having? Thanks in advance, Taki!
