解决GTASA在Windows10/11的兼容性问题

众所周知，GTASA Steam Version问题特别多。本文针对这种情况给出了如下的解决方案和优化思路。

如有其他疑问，可以参考https://www.pcgamingwiki.com/wiki/Grand_Theft_Auto:_San_Andreas

降级补丁

非常建议打降级补丁，因为GTASA Steam Version真的是出奇的烂。BUG一堆，而且因为版权问题缺少了很多资源。所以最好打降级补丁。如果本身就不是Steam Version，而且版本是v1.0，那么就不需要降级了。

下载GTASA Downgrader来降级：http://downgraders.rockstarvision.com/

将SA DOWNGRADER.rar的内容解压到游戏根目录下\Grand Theft Auto San Andreas：

运行install.bat程序，系统将会启动cmd窗口，待程序运行后，窗口就会自动关闭。于是就降级成功了。

在往后的游戏中，我们只需执行gta-sa.exe即可：

如何确定是否降级成功？如果打开游戏出现如下标志就算成功了：

如果游戏启动失败，你可能需要删掉游戏配置文件目录中的gta_sa.set，他一般位于：

%USERPROFILE%\Documents\GTA San Andreas User Files\gta_sa.set

其中%USERPROFILE%是指向用户主文件夹的环境变量，俗称“我的文档”的路径。

Silent Patch解决兼容性问题

如果不出意外，这个时候你就应该遇到鼠标不可用的问题了。不是你鼠标的问题，是早期版本的GTASA并没有适配大于2核的CPU，所以就有这样的问题。

不管怎么样，你都需要打个Silent Patch补丁。不止是因为它解决了鼠标不可用问题，他还修复了特别多的BUGS，比如万恶的锁25FPS的BUG（严格来说不算BUG，但比较恶心人）和切回游戏时鼠标指针乱飘无法控制的BUG等……

以下摘自官网的数据：

Featured fixes:

• 14ms frame delay has been removed. As a result, game now locks properly on 30 FPS instead of 25 FPS
• More precise frame limiter, reducing lag spikes a bit when playing with Frame Limiter on
• Game timers now tick in a more accurate manner, making them not freeze if framerate exceeds 1000 frames per second; in other words, this fixes occasional freezes on fadeouts if playing with Frame Limiter off

安装ASI Loader

安装Silent Patch之前，你需要ASI Loader，他是GTA脚本和mods的加载器，安装方法也非常简单。先从https://1drv.ms/u/s!AmZlhUlwACFugeJqDV40RgU5NAN9-g?e=dc3GRg 下载Ultimate ASI Loader（同样适用于Rockstar Games Launcher）

直接解压到游戏根目录\Grand Theft Auto San Andreas即可：

安装Silent Patch

接下来从https://cookieplmonster.github.io/mods/gta-sa/ 下载Silent Patch：

得到：

将除了Readme.txt以外的文件复制粘贴到\Grand Theft Auto San Andreas\scripts内：

进入游戏，如果你的鼠标问题解决了，就说明Silent Patch安装成功了。

提一嘴，Silent Patch同样解决了宽屏适配问题，16:9和16:10分辨率都能适配上了。但我还是建议专门装一个修复宽屏适配问题的插件，这一会在解释。

ThirteenAG’s Widescreen Fix

虽然Silent Patch修复了高分屏适配问题，但是效果比较一般般。比如游戏画面宽屏修复了，但是游戏UI却没有。ThirteenAG’s Widescreen Fix可以修复这个问题，其文件在github仓库里：https://github.com/ThirteenAG/WidescreenFixesPack/releases/tag/gtasa

下载后得到这样的文件：

注意，需要你提前安装ASI Loader。

直接copy到游戏根目录\Grand Theft Auto San Andreas即可。

高清加载

游戏内加载时的图片都比较模糊，可以替换成高清的。在ThirteenAG’s Widescreen Fix的Github仓库中还有个前端版本frontend，所以可以安装这个：

得到的如下的文件：

将他copy到\Grand Theft Auto San Andreas\models下替换原文件：

这样图片就是高清版本了，很有feel。

Chiri’s resolution forcing tool

GTASA默认的刷新率是60HZ，无论你的屏幕刷新率多高都是60HZ。Chiri’s resolution forcing tool可以修复（必须先装ThirteenAG’s Widescreen Fix）：https://helixmod.blogspot.com/2013/02/chiris-force-certain-resolutionhertz.html

得到如下文件：

将d3d9.dll和d3dx.ini复制到\Grand Theft Auto San Andreas

修改d3dx.ini中的refresh_rate即可：

无边框窗口化（与Chiri’s resolution forcing tool冲突）

在安装了ThirteenAG’s Widescreen Fix的条件下，在游戏根目录\Grand Theft Auto San Andreas下新建一个wndmode.ini文件即可实现无边框窗口化，但由于是窗口化，那么这个时候游戏的刷新率跟你的屏幕一致了，于是就不需要Chiri’s resolution forcing tool了。

ThirteenAG’s III.VC.SA.LimitAdjuster

ThirteenAG’s III.VC.SA.LimitAdjuster用于解决GTA的一些限制问题，比如帧数限制，内存限制、车辆限制等：https://github.com/ThirteenAG/III.VC.SA.LimitAdjuster/releases/

下载这个文件：

得到如下：

将文件复制到\Grand Theft Auto San Andreas\scripts即可

然后修改III.VC.SA.LimitAdjuster.ini文件，找到[SALIMITS]，里面的配置参数就是针对SA的。（这个补丁同样支持GTA3和GTAVC）。

其中：

分别修改帧数限制和内存限制。用这个补丁就可以让你的游戏达到60FPS了。

Project2DFX

Project2DFX用于解决GTA中远景渲染和灯光的问题，老版本中远景渲染比较垃圾（当时毕竟处于优化考虑，性能都不高）：https://thirteenag.github.io/p2dfx#about

下载后得到这个文件：

如果装了前面的LimitAdjuster，只需要将SALoadLights.*复制到\Grand Theft Auto San Andreas\scripts即可。
