nwn and Gtx 460 graphics card

[Legacy_Leinadi]

               I'm on a GTS450 card and I'm having similar problems. Haven't tried with robes or ranged weapons specifically but I was looking to play a module using custom content and I had the same kinda problem. As soon as I equip certain pieces of equipment, FPS drops very low. Take them off, FPS goes way up again.



Hope some good fix can come for this. I can't think of a more annoying computer problem than when you have new technology having problems with old games, it's very frustrating.

               Bump.



Guys and Girls, it's strange.



When i started campaing (without extension limit) i got 110-120 FPS (I got 460 GTX).



BUT when i started a server with CEP 2.1 on it i got only 15-20 FPS. I think the problem is no with NWN 1 but with CEP and items that it offers.

Unfortunately, no. The CEP simply contains a lot more content which uses the GL extensions which appear to have been deprecated in the never drivers.

I tried a very simple test - a stock NWN Diamond install, patched to 1.69, with no additional content. I opened several of the example modules (eg. the doors one, the cat lady). I selected a premade wizard character, then spawned a cloak. Equipping the cloak caused the FPS slowdown. Equipping a bow also caused slowdown. Heck, equipping one of the newer fancy robes for Wizards also caused the slowdown. Basically, it's a problem with the game/driver combination and even at minimum graphics settings it still happens.

               What kind of graphics engine alterations would need to be made in order to update NwN to something like OpenGL 2.1? Is something like that even within the realm of possibility for the nwn community, or is it illegal to tinker with the game in that way?

               Are Nvidia's drivers open source? If they are, then perhaps someone could create an OpenGL 1.5 driver for the new cards

               Right, there may be a way but I don't have a 400/500 series card to test it on. What you need is an OGL wrapper for DirectX. When Vista was released I believe the drivers that installed with Vista for most vid cards used an OGL wrapper for DX, which was why everyone needed to get proper drivers in there ASAP to get things up to max speed. I may be wrong however, it may have been a software OGL implementation which would be too slow. I don't think Win7 went down this route. If it was a DX wrapper get hold of the Vista one. If it was software in Vista, you'll need to find another DX OGL wrapper.

Last time I used an OGL wrapper it was to get OGL on a Voodoo card, so you'll have to do the research yourself. Still, the theory is sound.

I seem to remember that a company called Scitech used to make a wrapper called GLDirect, but that was a long time ago and I don't know if it ever got to OGL 1.5.

Either that or run it on a netbook with a Radeon HD 4552 with shiney water off and safe movies on. Fast at full settings.

               I'd prefer a solution which didn't require a wrapper. Linux doesn't have Direct3D and still has the same problem due to the fact the Linux/Windows NVIDIA drivers are basically the same, and so inherit the same benefits and flaws.

If someone was able to identify the GL calls which cause these performance regressions and develop a library to bypass it, that would work reasonably well until/unless NVIDIA releases a fixed driver. I know that at least with Linux a library could be inserted into the code via a LD_PRELOAD, which has been used with NWMovies and NWMouse. I imagine something similar would be quite possible in Windows as well.

In Windows, nope. In Linux there are the Nouveau drivers which are basically reverse engineered drivers developed by the wider community, but they don't yet work with the GTX 460. At this stage either someone makes a workaround that is applied to NWN or we wait and hope NVIDIA decides to fix things at their end.

Seems like a few other games are having problems with Nvidia's new cards.



Yet some of the people here seem to think that this is merely a driver issue isolated to NwN.

               Good evening everyone, I too like you are afflicted by this problem, and I'm looking at as many forums as possible allies for this cause.

One of my fellow-sufferer has opened a new thread here:



http://forums.nvidia...howtopic=188517



Where a technician has responded by saying that Nvidia are considering the issue.

So I ask you to write in that thread to be as many as possible.

Thank you for your attention, and hopefully we can play soon to our beloved NWN.

               The new Beta Drivers 266.35 doesn`t solve the problems with NWN,

in case anyone will ask if they do.

I installed them and tested around some stuff, sadly nothing.



Nvidia`s Release Notes are talking about performance gain on several

PC games, but no effect on NWN so far.

BUT, they fixed low fps bugs for crap like Final Fantasy XI... -.- lmao *bangs the head on the desk*

               I was on Nvidia's forums, and they said to check back in February, they're aware of the problem and looking into it.

               Just a post with the pertinent information I mentioned above.

[Legacy_Grieyls]

               Seems mid Feb, is the fix date... Here's hoping, I've been away from my NWN server for far too long because if this issue



On another note getting FPS drops in other games as well. I'd mention them but they are not boiware games so not sure if I woud cross aline there I shouldn't be. Anyway some of these games are only 3 yrs old or less. So... Mid feb [fingers crossed]

               I'm getting nearly identical issues. Been ripping my hair out about it, but can't do much at the moment. This is straight-up a driver problem, and not one we can fix (as of right now, at least).
