I've noticed Patch 1.0.4.0 is for Low-Med PCs.. It gives twice the (performance) speed than Patch 1.0.7.0

Patch 1.0.7.0 slows down the performance, Supports IV:MP.. Patch 1.0.4.0 doesn't support IV:MP.
Only GFWL (Games For Windows Live) Multiplayer/Log Me In Hamachi.

The Differences Between Patch 1.0.4.0 & Patch 1.0.7.0 :
- New Shadows (Like in GTA V & Other Latest RAGE Based Games) {Rockstar Advanced Game Engine}
- New Shaders (Known to cause lags on some NVIDIA GPUs, Shaders broke the performance)
- Enhanced Effects (Burnout Smokes, Fires. etc)
- Patch 1.0.7.0 replaces Texture Filtering options from Low-Highest to Trilinear-Anistropicx16
- Changes in Game User Interfaces (Pause Menu, etc)

This Fixes Only Applies To Low-Med Systems (Like you can only run the game at lowest settings & 30fps average)

How to get more FPS by forcing GTA IV to use ATI Shaders : (GPU must support both DX9 & DX10)
1. Go to "C:\Program Files\Rockstar Games\Grand Theft Auto IV\common\shaders" game directory.
2. Make a backup of all files & folders by simply Add to WinRAR Archives, Name it "backup.rar".. (Recommended)
3. Now, Go inside "win32_30_atidx10" folder & Copy everything.
4. Go back to "shaders" directory, then go inside "win32_30_nv8" folder.
5. Paste & Overwrite them all and back to "shaders" directory again.
6. Open "win32_30" folder and do the same thing, Paste & Overwrite everything. (May support to Intel GPUs)
7. Now go back to "Grand Theft Auto IV" game directory and open "commandline.txt"
8. Add "-availablevidmem 0.510 -percentvidmem 100 -novblank" options.
(Do Not Use "-norestrictions & -nomemrestrict" Options)
9. Save the file (commandline.txt).
10. Try Running A Benchmark & See What Happens :D

My Full PC Specs :
Motherboard - Intel(R) LGA 775
OS - Windows 7 Ultimate Service Pack 1 32-bit (6.1, Build 7601)
System Manufacturer & Model - Intel(R) AWRDACPI
BIOS - Phoenix Award v6.00PG
Processor - Intel(R) Pentium(R) 4 Dual-Core CPU E5200 @2.50GHz~
RAM/Memory - 2GB DDR2
Pagefile - 4GB, 1250MB Used
DirectX - DX9, DX10, DX11
GPU - ZOTAC NVIDIA GeForce 9500GT 1GB GDDR2/GDDR3 (1GB Dedicated VRAM + 776MB System VRAM)
Monitor - Acer P166HQL 1366x768 60Hz

In Patch 1.0.4.0, I can run GTA IV at Highest Settings with 25-30fps average.
Patch 1.0.7.0 slows down the performance, I run it @Highest Settings & i get 5fps only except in night time, Which gives me 15fps average. Even using ATI Shaders, It still lags :neutral2:

Can anyone help me why my GTA IV runs slow? 30fps isn't enough for me.
I know that i need more RAMs but my GPU is powerful enough to run it.. :neutral:
My PC passed CYRI (Can You Run It) Grand Theft Auto IV System Requirements Tests but it still lags.

Thanks for your times reading this! :) Also Thanks in advance for helping me :D

Also remember that, IV is a bad ported game..

Those cdimages were maybe from PlayStation file systems,
Rockstar is like using an Emulator to run the game :\

Note the shadows uses a lot GPU Dedicated RAMemory (RA=Random Access)
Shadows in Patch 1.0.4.0 were blurry & In Patch 1.0.7.0 it doesn't, Because it has new Shader Systems
Like used in GTA V & Other RAGEngine Based Games (RAG=Rockstar Advanced Game)

Am i right or wrong? :D
