我非常喜歡雪地奔馳這款游戲，買sd的一部分也是為了它。可在我打開這個游戲時，游戲發生閃退問題。查閱了網絡各個途徑，基本沒有解決方法。因此我自己分析終于解決該問題。以下是我解決問題的思路，僅供記錄參考：
游戲在崩潰時會生成一個文件“CrashDump.dmp”，使用WinDbg讀取dmp文件，并使用分析命令，我們會得到一長串的報錯信息。

顯然，報錯信息的核心在于：
IMAGE_NAME: atidxx64.dll
報錯關鍵點在于：
FAILURE_BUCKET_ID: NULL_CLASS_PTR_READ_c0000005_atidxx64.dll!Unknown
此處我根據曾經的經驗直接上網搜索了atidxx64.dll，下載放到系統文件里進行替換，結果就是顯卡驅動損壞。這才知道這是AMD的驅動dll文件，因此到steam官網下載最新驅動重裝了顯卡驅動。思索接下來如何進行處理。
由代碼看很顯然是因為AMD的顯卡驅動出現非法訪問內存的錯誤導致整個游戲直接崩潰，而這個游戲在SteamOS可以正常運行。SteamOS主要使用Vulkan來驅動游戲，會不會是因為這個游戲不適配D3D導致的呢？
在github正好有一個叫dxvk的庫，能夠基于vulkan實現d3d11，因此我們訪問https://github.com/doitsujin/dxvk，從 Releases下載dxvk-2.3.1.tar.gz（當前最新版本），解壓壓縮包，在x64 目錄中獲取 dxgi.dll 和 d3d11.dll，并將兩個dll文件放進Snowrunner.exe根目錄所在的位置，再次啟動游戲，游戲果然正常運行了。
困擾我兩天的問題終于解決了，也算這個小眾游戲全網的第一個解決方案吧。
