what about the nonagp settings...how do we determine safe changes..I really hate trial and error on this
Voi~~~ I seem to remember hearing how NFS Hot pursuit and XP just refuse to get along....The newest underground 2 is a killer game.....
Nealh the newbie......welcome, LoL, but you need to post your specs. or at the least let these wonderfully helpfull gurus know what videocard you have. Trial and error....thats gonna get you in trouble bigtime. Just leave em at 32 and if the Video card is any higher than 128, set it to 128. don't bother with anything else. good luck
PCI Latency is defined as "the maximum length of time the device has to terminate the transfer and to relinquish the control, when there is another device requesting the control of the PCI Bus." The time is measured in bus cycles. Setting this value smaller allows better multitasking on PCI bus, when multiple devices are requesting the bus. However, smaller value will also decreases the throughput of the bus as there is some overhead occured for each transfer to start.
The reason behind this phenomenum is unclear. Maybe the graphics card needs to send something to memory frequently so the program can determine the state of the current rendering and put the next set of data to the graphics card's texture memory. As this happens, AGP needs to be turned around.... from writing to graphics card to reading from graphics card. If the PCI latency is high, the delay for that read is long, so the program is stalled. If this is the case, then changing from AGP to PCIe will help and a speed up can be seen. This is because PCIe has dedicated channel for each direction of transfer, eliminating bus-turnaround and the fight for bus. However I am not a designer of graphics hardware I can't not tell which causes this phenomenum. It is just purely my speculation.
Hm interesting. BTW I think that the main reason some new cards has ultra high latencies is becuase it increases their amount of FPS. This means that the competetive numbers looks better... However, when it comes to game experience having a high FPS isn't everything... smothness and good sound quality is two other things that has to be taken into account.
Cool, I set the vga and sound latency to 64 and it made a good difference. Games are smoother and my sound is noticably better(no more popping!). Thanks for the great tip
Truely amazing!! I would highly recommend this for people who bought that crazy expensive piece of a video card and want to see NFSU2 work amazingly better. I have been overall dissatisifed with the performance of NFSU2 until now! Do you feel that the U.R.L races are lagging and almost feel like your system can't handle the graphics? Fear not, after I set my Latency to 64 it played soooo much smoother. There is the area on the map where you are driving through a bunch of lights hanging (kind of like a mini las vegas feel). I used to be able to notice the dip in my system performance when I hit that area... not anymore! I honestly know that I'm not just seeing things, or think it's better cause I want it to be. I don't play to many games to test out what else has improved. Now I feel more like I spent my money for a reason.. heh
If you have no other devices installed in the PCI slots, is there any benefit then of changing the latencies with this tool?
You know... that's a good question D. I noticed that all my other PCI devices were set to 32 already, so I didn't want to risk setting anything else lower. Lots of people in this thread said that 32 is the stopping point on the low end. On another note though, this is definitely a "try at your own risk" program. I don't know if it was a fluke, but I was playing an online game and got a really nasty system crash. I'm going to do more thorough tests to make sure that my system is still stable with the 64 setting. I may move it up to 128 and see if that helps if the system acts unstable.
To make matters even more weird. Creative recommended me to test different settings from 0 to 32 on my Audigy 2 zs plat pro to see if the "pops" whent away... (yes even try 0).
I went through the whole thread but couldn't find the answer, should I change it even for a PCI-E card? When i run the tool, Everything including the video card is set at 000 , with the exception of my tv tuner card and my soundcard hardware is set at 64. Should i change anything?
trial and error with PCIe,not sure if it has been tested on the PCIe yet or what the numbers should be.
Supposedly there's a slight drop in frames, but in doing so it smooths out the frames, making gameplay more smooth.
My motherboard is fairly outdated (P4X266), and has no option to change the latency. Is there any risk of damaging it if I use this program to lower the video card's latency?
Dias, my experience is a 500 aquamark drop in my GFX cards Safe mode. That not much considering that my Aquamark score is around 65000 in safe mode.
The Gainward Golden Sample cards has a safe mode and an enhanced mode. Safe mode: 400/1100 Enhanced mode: 430/1200
just started reading this today and going to try it tonight,but something i havnt seen any 1 coment on yet is the biggest game rt now thats having all theses stuttering problems....EVERQUEST2. has any 1 who plays eq2 tryed this yet for the 6800 stuttering problems that has been 1 of the biggest gripes since the game came out.
