More likely just another 'win' for crappy VIA chipsets and their godawful AGP - turns into a running battle between the card (8x), the board BIOS (4x) & the nvidia drivers (2x) for supremacy. There was a registry fix that sometimes worked / sometimes didn't (think it was part of the VIA 4-in-1 package or one of the card tuning apps).

The first concern should be stability.

If it works, I would not fight it and leave it at 2X . If it does not work at 2x, running it faster (4x) will not improve it (prevent it from crashing) and 2x likely won't be much of a bottleneck, if at all on your system anyway. If you have not already done so, make sure to install VIA 4-in-1 drivers appropriate for your OS and chipset.

Before you do any changes from a working or mostly working state, I suggest making a backup, as it makes reverting easier and faster in case you need to do trial and error to find the best Nvidia and VIA 4-in-1 driver combination for your setup.

It seems to work well at 2x, i asked because i have to be honest, Deus ex is making my life kinda hellish, so i though "could it be the AGP ?" then again no other game gives me issues and if i use opengl or nglide the game works without freezes, it's just D3D.

Use RivaTuner to enable 4x and FastWrites.

I second RivaTuner

Nope it doesn't work, i can only go up to 2x, even with rivatuner i can't enable fastwrites at 4x and overall any use of d3d crashes the system with agp at 4x.

Do you have VIA 4-in-1 drivers installed ?

There was a registry patch making the rounds in the past that may work:

; For Win9x/WinME
[HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System]
"EnableVia4x"=dword:00000001

To go back to AGP 2x:
; For Win9x/WinME
[HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System]
"EnableVia4x"=dword:00000000

I would guess that this is what Rivatuner does .

Oh, ok.... I do not know what Rivatuner does; used it maybe only once long ago. This patch did work though.

Great. And what do you get performance-wise?

Since the very beginning yeah.

Apparently, some versions of 4-in-1 drivers work better with certain chipsets.

I use v4.43 on my KT7A and never had any issues with AGP 8x cards, despite my board only supporting 4x. Your chipset is different though.

The board was retired because of PS2 I/O malfunction and I did not test 2x/4x AGP speeds at the time.
But here a benchmark note as indication:
XFX ti 4200 / ASUS CUV4X / 850/100 MHz FCPGA@1.133/133
3DMark2001 @ 1024x768x32 / score 7102

That's ME it could behave differently from my C version.

For WinME i can only find these 3 https://www.asus.com/supportonly/CUV4X-C/HelpDesk_Download/ i'm currently using the 4.37V version, i don't know if using the previous driver will help.

Try these:

According to some posts here, that version should be good for your Apollo Pro chipset as well.

Thank you, also as an update, i installed the game on my Athlon XP PC in the sign on the partition with WinME on and it works buttery smooth all maxed out, i used only the goty patch and the standard d3D renderer.

Nope, still totally unstable at 4x, i'm starting to believe that a card meant for agp8x is just unstable on this motherboard.

Can you try setting it to AGP 1x ? That's what it took to get a Radeon 9700 (8x) on my 440BX (2x) board stable .
