占用率也异常低，GPU 20%左右

无解了吗

Hi there guys!
I've taken a chance to read through your discussions, and you bring up some great points and workaround. Thanks for sharing your experiences during your own investigations into this.
Thanks to those who have already tried troubleshooting steps. If you have not already, I suggest that you check out this article and following the steps. In particular, I recommend ensuring that you disable background applications, as these can interfere with the game files and cause low FPS and crashes. In particular, we've noticed that hardware monitoring software, like MSI Afterburner, can cause these conflicts, so I'd really advise trying this step.
If you're still having issues, I ask that contact our team directly so we can take a look at your system files. You can open a support case here, or contact us via live chat, Twitter or Facebook. Please ensure you have an MSinfo and DxDiag ready to upload to your case, and be sure to include all troubleshooting steps you have tried so far in your case notes! This will help us in our investigations.

等修复 这个问题自vulkan出来以后一直存在

我用vulkan只有6帧....

现在依旧突然掉帧

好像是驱动问题，上次更新驱动后有一次就不对了，然后就把显卡驱动退回上一版本后暂时无恙

爆显存了，我3080用vulkan玩十几分钟直接变2帧，用DX11就是正常的不会爆，4K+全部极限画质。我浪遍所有3A，GTA5开8XMSAA都不会爆，最后就折在断点上了，育碧喜欢用高纹理高分辨率的贴图，还有就是这游戏的体积雾开极限直接吃5G显存。

这两个模式只有帧数上的差别吧，没有画质上的差别吧？我是新入坑的，我看开了v的，60几，不开也有50多提升，不超过十针，五针左右，那如果开V只有帧数上的提升，那我还是不开算了，他太容易掉帧数了，突然就掉了20几针，要等半天才变正常
