画质党狂喜！英伟达DLSS 4.5光线重建8月25日发布：RTX 20到50全系免费升级_我的网站

千王之王重出江湖

一 | 英伟达官方近日宣布，GeForce On社区更新直播将于北京时间8月25日23:00在YouTube和Twitch平台播出。 Colombo, Oct 20 (UNI) The Supreme Court has re-issued notices to former Sri Lankan President Gotabaya Rajapaksa regarding a petition filed over the disappearance of two human rights activists in Jaffna peninsula in December 2011.
The notice is returnable on December 15, The Island newspaper reported on Thursday.
The Court of Appeal earlier quashed summons issued on the former President to appear before the Jaffna Magistrate’s Court, as a witness, in connection with this case. Both the missing activists are Tamil.
The Sri Lankan military is accused of killing thousands of innocent civilians during the end stages of its war against the Tamil Tiger separatists. Many were also picked up for questioning but were never seen again.
Former President Gotabaya Rajapaksa, who fled Sri Lanka in July but has since returned to the country, presided over the war against the Tamil Tigers as the country's Defence Secretary.
UNI MR。业界普遍预期，DLSS 4.5光线重建的正式推送将是本次活动的核心内容。

二 | 对于光线追踪和路径追踪游戏玩家来说，这无疑是一次值得期待的画质升级。

三 | 英伟达于今年6月在COMPUTEX 2026上正式发布了DLSS 4.5光线重建技术。该技术采用第二代Transformer AI模型，相比前代，新模型计算能力提升35%，参数数量增加20%，降噪器更强大，空间感知能力更深入。此前，DLSS 4.5光线重建的相关文件已在《使命召唤：现代战争4》测试版文件中被发现。其驱动文件通过NVIDIA Profile Inspector即可在已支持游戏中提前启用。正式推送在即，用户无需更换硬件就能升级，DLSS 4.5光线重建将覆盖RTX 20、30、40、50全系显卡。由于RTX 40和50系列支持FP8精度加速，运行光线重建的效率更高；而RTX 20和30系列不支持FP8，性能开销会相对更大。此外，新版光线重建在RTX 50系列上还支持6倍多帧生成，这是一个专为50系优化的功能，能进一步放大帧率表现。

四 | 除DLSS 4.5外，本次GeForce On还可能涉及RTX Spark和Reflex 2等话题。关于DLSS 5，英伟达今年3月GTC上已宣布计划秋季推出。至于新硬件方面，2025年Gamescom曾明确宣布无新硬件，今年英伟达虽未作类似说明，但目前尚无新GPU迹象。
