[解決] 画面が一切表示されない

[ikadzuchi]

Steamライブラリから「プレイ」、またはexeファイルを実行。
タスクバーにアイコンは表示されるが、ウィンドウは表示されない。
しばらくしてメニューUIのような音がする。この時点で矢印キーやマウスに反応してメニューUIのような音がする。
Enterを押すと音楽が流れ、ゲームが開始しているように思える。
タスクバーのアイコンにマウスホバーでサムネイルを見ると、真っ白。
PCの再起動、ゲームのアンインストール・再インストールを試し、変わらず。
今日アップデートがインストールされたが、その前後で変わらず。

Navigate to your graphics adapter control panel, then find 「Display scaling」 option; change it to 「Maintain aspect ratio」.

[ikadzuchi]

Thank you, It works!
In 「NVIDIAコントロールパネル」→「デスクトップのサイズと位置の調整」, the 「スケーリング」 setting is already set to 「縦横比」, which I think is the same as 「Maintain aspect ratio」.
So I changed it to 「全画面表示」 and now the program run properly.
I don't see which is right but anyway it works.

Thank you, It works!
