私は、周期表のレンダリングを含む学校向けの小さなプロジェクトをまとめています。私はこれを行うためにLWJGLを使用することを選択しました。しかし問題は、私がテーブルをレンダリングすると、ゲームは30fps（60fpsで上限）から始まり、すぐに1桁のfpsに変動します。私はこの問題がメモリリークの可能性があると確信していますが、わかりません。誰も私のコードで目障りな問題を見ることができますか？私のLWJGLゲームのパフォーマンスを向上させる最も良い方法は？

私は知っている、それは多くのコードですが、誰かが私を助けることができれば大いに感謝するでしょう。
ありがとう、Flafla2。
あなたはメモリリークを言う、あなたは利用状況を見てみましたか？あなたはベクトルをたくさん新しくしています。これは普通で罰金ですが、それは私が見ている最初の場所です。可能であれば、CPUとメモリの使用状況をプロファイリングして、ホットスポットの位置を確認してください。ただし、CPU *上でレンダリングコード*をプロファイリングすると、間違ったデータが提供され、ほとんど無視されるはずです（ドライバ/カードバッファはCPUプロファイルが一致しないようにバッファします）。 – ssube
ありがとう、私は今プロファイリングしようとする（前にプロファイラに問題があった、私は問題を解決することができますが表示されます）。 – Flafla2
申し訳ありませんが、問題が見つかりました。 'TextureLoader.java'では、' glDeleteTextures（textureID） 'を使わなかったので、' Font.java'で使われたテクスチャはメモリからアンロードされていませんでした。今、私は安定した50 + fpsを取得しています（私の馬鹿げたMacbookで、もちろん）。あなたの助けをありがとう！ – Flafla2
