First of all, English is not my native language, so please probably associate what I am saying. First, I will tell you the answer first. Modify the shader cache in the nvidia graphics card options, change the default option to 10G, turn the triple buffering option on, and change the vertical sync to fast, and you'll be able to experience 60fps at 30fps in SC. A few versions ago, the nvidia graphics driver changed the shader cache setting content from on and off to set size. So being a practionist, I tried all the size settings and came to the following conclusion. Default: That's what people usually use, lag, screen tearing, and transients. 128M-5g: not much difference, but the lag will be reduced. 10G: perfect, lag, screen tearing, transient are gone, the screen is smooth like a stocking. 100g: memory explosion, extensive use of virtual memory virtual memory, screen lag. Unlimited: virtual memory explosion, finally used up all the space on my C drive, lag. I don't know what the principle is, but after changing to 10G, the screen is very smooth, a smooth screen I've never experienced before! NVIDIA Control Panel - Manage 3D Settings - Shader Cache Size Latest Feedback Triple cushioning may not be effective Vertical sync on fast, for many low fps players can reduce sluggishness and screen tearing, and will not affect the performance. 10g currently works better for users with more than 32g physical memory, but you need to set the best virtual memory above 10g, otherwise the showroom in NB will cause flashbacks. For players with 16g physical memory, try using 1g or 5g shader rendering size. It is not clear why, we suggest you try it yourself, switch between 1g, 5g, 10g and 100g shader rendering size to experiment, and adjust your virtual memory size to find the right size for your computer hardware by yourself. Thanks for the feedback from the citizens in the reply! Some players open the vertical synchronization to fast after the screen will appear shaky, this time modified to adaptive may make the screen becomes very smooth, and there are no more cases, you can try ~ New possibility: this setting may be more useful for 32g RAM or laptops I have a possibly reasonable explanation https://robertsspaceindustries.com/spectrum/community/SC/forum/3/thread/this-could-be-a-reasonable-explanation-for-the-fps/294227 For users of AMD graphics cards and old nvidia graphics cards. In one of the threads, I seem to remember seeing an old way to change the access to the shader cache folder to disable delete operations, which should also do the trick. This may work for some users who can't update the latest NVIDIA drivers or AMD cards, but I'm not sure where the specific shader cache is located, it seems that different driver versions have different locations for shader cache. In a reply to my other thread, a player with a Linux operating system gave feedback on modifications that could be made on a linux system that would serve a similar purpose.
