View Full Version : Do the dual core changes effect the nvidia drivers?

<p>Nvidia drivers can multithread, but EQ2 is forced to always run on cpu0. So question is does that forcing of eq2 to run on just 1 cpu also effect the nvidia drivers rendering it? After LU28 a number of us noticed a drop in perfomance which shouldn't logically happen, eq2 is still getting 100% cpu power just no longer 50% of it from each cpu. (BTW the change does make the chip hotter, thanks for that)</p><p>Anyway yeah I know the issue is old but I still want it fixed, I miss running in high quality with shadows and having smooth fps. Now it's balanced or less to run through Antonica when it's empty.</p><p>No I don't have spyware/firewall issues/a dead hampster/whatever, the drop in performance was directly related to this change. Was fine before, sucked afterwards.</p>

ahhh...like this topic New Forum, new Question. What about Dual Core advantage using by everquest2.exe? Or maybe just no force to one core. Intel doesn´t have a prob like AMD. Why are we forced to use one core? If the game can´t handle let windows handle it - like before LU 28. thx <img src="/smilies/8a80c6485cd926be453217d59a84a888.gif" border="0" alt="SMILEY" />

Dual core/X2 is nothing new, it has been around for years in the form of SMP capable motherboards, you can still count on one hand the number of true parallel processing games out on the market that where designed from the ground up to utilize this technology. The game takes advantage of multiple processors at the server level which is more important - at the client level you major bottle neck will be the net interface. It does not matter if you client pc can process the code in nano-seconds while it is sitting in a system wait state for the required data to make the round trip from your pc to the server and back to get a update. Not a new question also, these discussions go back to when the X2 was released. Not even Vanguard is parallel processing enabled and it came out 15 days ago.</p>

Whatever... Before LU28 the performace of Dual Core PC´s was better - this is fact...and this is what I and a lot other players want back.

Yes we all know eq2 wasn't a multitreaded application etc etc, but it did load balance across both chips and now it doesn't. Now it's hard forced to run on the first cpu which maxes it out while the other is left unused. While their change doesn't seem to make much different eq2 seems to be only able to grab 80% of cpu0 instead of say 50% of each. Also it seems with the changes the nvidia drivers are no longer multithreading either as cpu1 literally is setting at 3% or so.

Sigh.. not this again...   If EQ2 is only taking up 80% of a core, you have some other issue... either an IO bottleneck somewhere, or some other app is causing problems.  The nvidia drivers are kernel level drivers (in XP atleast).  Any processing that is done by them, is done wherever the OS puts the driver, regardless of the affinity selection on a given application.  Note - The parralelism in the nvidia driver is related to the driver<->card interface (allowing the game to continue while the card is communicating with the driver).  This requires little to no CPU time, as it is mostly idle IO/wait cycles.  It does however allow the application to continue on its way without IO blocking. For the vast majority of people, the dual core changes made no difference at all in performance, usingeither nvidia or ATI cards (I run on an X2/Nvidia, C2D/Nvidia and P4D/ATI with no degradation in performance).  Many people have even fixed their post LU-28 performance problems by updating drivers, or other fixes... --Ruab
