# VRAM 使用率超高

## 症狀

裝了 iStat Menus 後，有觀察到剛開機時顯卡記憶體使用率超高，導致畫面 Lag，可是在睡眠喚醒後，使用率會降低到一半以下，直覺就是有東西卡住那些 VRAM

總之加了一個 Kext 和一些 Flags 後，這事就解決了

## 解法

### 加Kext

不意外的，就是 [NvidiaGraphicsFixUp](https://github.com/lvs1974/NvidiaGraphicsFixup/releases)

除了加 NvidiaGraphicsFixUp 之外，記得也要更新 Lilu 喔

{% endhint %}

安裝很簡單，就丟進 EFI/EFI/CLOVER/kexts/10.12

### Boot Flags

開啟 Clover Configurator，在 Boot 頁面中的 Custom Flags 加入

`-ngfxbeta`

`-ngfxgl=1`

`-ngfxcompat=1`

## 後記

作者提供的 Flags 很多，我也試了很多，總之這樣搞之後 VRAM 使用率就下降了，目前使用上也沒什麼問題

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mtwstudio.gitbook.io/ryzentosh/bugs/high-vram.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
