HDR shows a black and white image with HDR enabled as per the attached. This is with a clean install of build 494 and a clean Nvidia driver install 334.89. No vmods or additional tracks installed. HDR FPS also very low (13-14 FPS). Colors are normal with HDR turned off. FPS between 43-49 @ Silverstone & Lime Rock tracks with 10 AI. 3x Titan SLI & 3x Dell U2713HM monitors. Sig has full equipment details. View attachment 11826
13 FPS, and only 43-49 FPS w/ multiview off, WITH 3 NVIDIA TITANS????? I'm thinking about going for a dual 780ti setup and have triple monitors and can barely handle playing with multiview off. ISI really, really, really, really, really need to fix this, not just the absolutely horrendous SLI scaling, but also the insanely low FPS with triple monitors (regardless of HDR on or off, and regardless of using an SLI or single card setup). They really need this as one of their top priorities.
Thank you. Any additional information on improving multi-gpu + multi-view + multi-monitor performance? Regards
The HDR color issue will require an update to the .exe by ISI. The multi-gpu + multi-vew + HDR performance issue has been there for quite a few .exe releases and does not appear to have been addressed so far. The only way to get useable frame rates with a multi-gpu, multi-view setup (at least with Nvidia drivers) is to leave HDR turned off for now. Multi-gpu, single screen acceleration + HDR offers useable frame rates but there is at least a 30 - 50% frame rate penalty with Nvidia drivers depending on screen resolution. Higher resolutions have a greater fps penalty. Environmental and road reflections in combination with HDR also have substantial fps drops with multi-gpu, multi-view setups. The general FPS tips offered in this thread: http://isiforums.net/f/showthread.php/18712-IS-NVIDIA-Image-Quality-A-Joke-Or-Is-It-Just-Me should result in the best combination of fps/image quality at the moment.
