快科技6月29日消息,NVIDIA DLSS技术即将迎来重大更新,将采用全新的 "Transformer模型",预计将带来诸多改进,包括显存占用量大幅降低。
目前NVIDIA DLSS技术基于卷积神经网络(CNN),而新的Transformer模型则是一种更先进的技术,据NVIDIA官方消息,新模型已结束测试阶段,将正式推出。
与旧版相比,新模型在显存使用上进行了优化,以1080p分辨率为例,新的310.3.0 SDK版本在使用Transformer模型时仅需87.77MB显存,比之前减少了19.8%。
这一显存降低的效果在其他分辨率,如1440p、4K和8K上也普遍存在,平均显存需求降低了约20%。
这意味着,对于那些显存容量有限(如8GB)的用户来说,使用DLSS技术时将更加轻松。
此外,Transformer模型通过评估每一帧中的所有像素,并理解单个像素的重要性,从而生成更详细的像素,提升画质,这将使DLSS在图像质量上也有显著提升。
不过需要注意的是,模型的显存占用总体来看并不大,在8GB显存和1080p分辨率下,模型的显存占用率约为1%,4K分辨率下也仅占用300M左右显存。
