01.为什么 GTA IV 在 PC 上运行如此糟糕?

GTA IV 于 2008 年发布,是针对 DirectX 9 制作的。Windows 10 和 11 无法很好地处理游戏的旧绘图调用,导致即使在 RTX 4090 上也会出现滞后。此外,该游戏与具有多个内核的处理器存在冲突。

02.DXVK(Vulkan)的奇迹

只需这一步,您的 FPS 就会增加三倍。它将游戏从 DX9 转换为 Vulkan。

  1. 下载DXVK来自官方GitHub。
  2. 提取d3d9.dll和dllx32 文件夹中的文件。
  3. 将这些文件粘贴到主游戏文件夹中(其中GTAIV.exe位于)。
  4. 打开游戏。您会注意到 GPU 使用率将会上升,并且 FPS 将变得更加稳定。

03.GTA IV FusionFix:强制 Mod

FusionFix 修复了 Rockstar 从未修复过的错误,例如长宽比和闪烁的阴影。

  • 修复了路灯远距离消失的问题。
  • 允许您自动跳过无聊的介绍。
  • 修复了 4K 分辨率下的十字线错误。
  • 只需下载 .zip 文件并将内容放入游戏文件夹中即可。

04.修复内存错误 (VRAM)

如果游戏提示您没有足够的视频内存(即使您有 8GB),请创建一个名为的文本文件命令行.txt在游戏文件夹中并将其粘贴到其中:
