The term "legacy" is used because the code was optimized for the GPUs that were available when it was written, a number of years ago.
Since VEGAS Pro 14 build 201, GPU rendering must be enabled here: " Options" menu > " Preferences" > " General" > " Allow legacy GPU rendering". In Vegas Pro 11 to 13, the GPU rendering options were diplayed by default. The two AVC/AAC encoders available in VEGAS allow GPU-accelerated rendering, which is a different thing from GPU acceleration of video processing explained above in part 1. They may also work better with Nvidia GPUs anyway.
Some VEGAS FX that were purchased from Velvetmatter cause VEGAS to crash with some AMD drivers more recent than 16.10.1.There are some reports of NVIDIA drivers improving in terms of OpenCL performance ( example 1, example 2).AMD Vega is due for release in 2017 and may perform very well with VEGAS.I successfully edit UHD video in VEGAS without it using my Intel i7-5960X processor, and there are other alternatives to speed things up such as proxy editing.
There is a particular problem with Nvidia driver 378.66. If your preview window is blank with an NVIDIA card, there are reports that this can be solved by installing a CUDA Toolkit.Please post your own reports of success or failure in a comment on that post. A spreadsheet of "good" and "bad" NVIDIA drivers for VEGAS can be found via this post.GTX 745, GT 730) cannot be recognized by VEGAS with certain drivers and the driver may need to be rolled back. Display Driver Uninstaller can help with a clean uninstall. In some cases the driver may need to be rolled back to an earlier version.
If so, update your driver from the manufacturer's website or from the NVIDIA or AMD website.
AMD FirePro - These workstation cards may work OK but most users choose Radeon.ġd.Choice of driver may make a huge difference in Quadro performance ( example). AMD Radeon gives more acceleration for less expense. NVIDIA Quadro - Unless you specifically need NVIDIA 3D Vision live preview, which requires a Quadro card, or ( debateably) 10-bit montitoring.NVIDIA GeForce GTX - Except GTX 580 and earlier, specifically for MainConcept AVC GPU rendering (see below).The following GPUs/graphics cards have been known to give disappointing performance with VEGAS Pro 11-14 (of course your decision may be affected by other applications which work well with these cards): Presumably similar variants of those cards will also perform well.ġc. AMD Radeon HD6970/6870/5870 (now old but good for MainConcept AVC GPU rendering).RX 480 vs NVIDIA GTX 970 (followed by stability discussion).The following GPUs/graphics cards have been known to work well with VEGAS Pro 11-14: Graphics cards that work well for GPU acceleration of video processingĪlthough both AMD and NVIDIA GPUs support OpenCL, AMD's implementation is stronger. You will need to restart VEGAS after changing the setting.ġb. GPU acceleration of video processing is enabled or disabled here: " Options" menu > " Preferences" > " Video" > " GPU acceleration of video processing". Enabling GPU acceleration of video processing It uses it to accelerate playback of the timeline and GPU-enabled FX.ġa. GPU acceleration was first introduced in Vegas Pro 11 and has not been significantly updated since, but it can still bring significant benefits with the right graphics card. Comment from MAGIX staff about current GPU development.Any improvement in rendering speed with Vegas Pro 15?.Clearly the changes in VP15 may affect recommendations for choice of GPU and CPU. In the meantime, it remains out of date and applies to VP14 and earlier. This FAQ post will be updated to reflect these changes when their effects are better understood. For VEGAS Pro 15, the general recommendation is now to keep GPU drivers as up-to-date as possible.QSV is now an option for GPU acceleration of video processing.The MainConcept AVC/AAC encoder has been replaced with the MAGIX AVC/AAC encoder, which inherits the same functionality and adds rendering acceleration via QSV or NVIDIA NVENC ( supported NVIDIA GPUs).
