Quake 4 Performance 8800GTS OC'D

braz2kuk · 7 May 2007 at 16:28

Hi,

I have got a BFG 8800 640mb GTS " 635/920 it is a great card and plays all my games to a good standard at my res of 1280 x 1024. however if i tell quake 4 to use 'Ultra High Qaulity' settings settings then the card struggles even if the game is using both cores of my oc'd E6600, does this sound right?

I know my card is fine as it plays everything else with no problem just wondered if anyone had any ideas about this?

Thanks

I'm sure I remember reading somewhere that Q4 performance goes through the floor when using ultra high quality textures and AA at the same time. Could be wrong though and I can't lay my hands on the source atm.

Yes, I remember reading that. I'm pretty sure it also said that the high quality settings were almost exactly the same, except they use compressed instead of uncompressed textures.

I must say I can play it absolutley fine. This is on my non-oc'd card and with 8Q AA / 16xAF. This is with Ultra as well?!?

Is the game patched to the latest version for you?

My old P4 3gig w/ 2gigs of RAM and a 512Mb 6800 can run quake 4 in ultra quality with decent fps almost manages to hold 60fps at 1024x with no AA and is still mostly abover 30 at 1280x with 2x AA... on the sig in my rig I can run 1440x with 4x AA and 16x AF and ultra quality and never drop below 60fps...

Oh yes. I forgot to mention that the stuff about bad performance on ultra high was more related to having only 320mb of RAM, so thats probably not the problem.

It's the same with Doom3.... frame rates are basically cut in half if you use Ultra High over High Settings...

I run Q4 on Ultra fine on my x1950pro.

I cant even play Quake 4 on high settings with 16xAA/AF, I get super lag of around 11fps.

Weird for me tho how I get bad performance with Pray and Quake 4, both use the same engine too :confused:

Yeah my X1950 with 128MB less graphics memory runs Quake 4 fine in Ultra high settings.

Are you sure you don't have the 320MB version? The 320MB version blows chunks in Ultra quality in Quake 4.

Other than that i'd have to assume driver fault somewhere. Are you using Vista?

Perhaps the move to dual core and an extra Gig of mem may help.

If I recall, Q4 is quite dependant on the amount of graphics card memory.

Sure used all my 1gb though

Graph of Quake 4 memory useage, both physical and vram, in real Ultra settings... anyone who says they are playing quake 4 on a 256Mb or 320Mb card in ultra settings and getting smooth gameplay is either lying, has texture compression enabled either ingame or forced in the drivers (in which case they are only running high quality even if it says ultra in the menu) or they have some extremely fast physical RAM (i.e. DDR3 which isn't out yet, with very high bandwidth).

oh apologies tute I mis-read what you were saying...

Lyon85 · 8 May 2007 at 00:44

What difference is there to the human eye going from ultra to high? I get 30fps @ 1680x1050 with 2xAA with the dual core patch (512mb card). I'd love to play at 60fps, but I'm a sucker for eye candy (not that I EVER play the game, I just like to know

).

You did have me confused, I was repeatedly reading what i'd said to see if i'd misspelt or said something wrong, lol.

Rroff · 8 May 2007 at 01:09

Theres practically no difference unless you stop and study the textures close up (then you can see the compression artifacts if you really look for them) afaik ultra quality doesn't use any higher detail models, etc. in quake 4
