Way too slow performance

I have upgraded my computer since i was hoping for better framerates in TRS, But since i upgraded from a 7900GT and an Athlon 64 X2 4400+ to todays top-of-the-line AMD Phenom 64 9850 2.5Ghz, MSI K9A2 platinum and 2x Sapphire Radeon HD3870 512Mb There is NO detectable improvement!!!

My laptop running AMD turion 64 1.6Ghz and 7600 GT GO is actually getting better performance!!!???

All other games work fine and fast, Newest drivers are installed, clean and responsive XP install, most recent MB BIOS.

Could there be a compatibility issue with XP X64 edition? which i am running to take advantage of my 4GB ram (it's so cheap nowadays)


PS: is there a theoretical limit to the number of addons for TRS?
 
Windows XP64 could very well be an issue, the drivers for XP64 are highly inefficient, even for the HD3870's

Also Trainz is NOT a multi-threaded application so it's not taking any advantage of your quad core (nor was it taking advantage of your dual core)
Trainz is also not a multi-gpu application. So it's not really getting a huge boost from the Crossfire HD3870.

What kind of framerates you seeing now and before?
And no there isn't a limit to the asset count, but at 99,000 my CMP is a bit slower than some.

Hi randknu

Check out these posts ( re upgrades & performance )

I have some info on duel core cpu & duel card performance from my system ( seems like my GPU upgrade was the one for me rather than cpu)
post # 43

There is also ma link on #44 to bench mark your system

I solved it! GP_38-2 put me on the idea that i might try disabling the crossfire...

voila constant 30+ fps! :udrool:

I guess auran has some compatibility work to do in future versions.

Future computers will have multiple cores and gpus so better to start writing code right away...:p

Quake 4 got multi cpu capable with a patch...

Oh and trainz will make good use of a dual core cpu, or, atleast windows will, as my trainz session would completely stop when avast antivirus suddenly decided it was time to update. after getting the dual core i can't even detect the update until i get the audible signal.
 
With a dual core and quad core you can assign processes to use different cores than the one used by a game, thus relieving some stress. The only downside is even Vista doesn't remember those settings so they must be re-set every time you boot up.

One thing to remember is that the nVidia 8xxxx and 9xxxx series, and the ATI HD xxxx series are DX10, and both companies are still working out bugs in the drivers (in ATI's case it's more inefficient, nVidia just plain doesn't work sometimes).

Also, that's debatable, as technology gets better you'll once again see it getting smaller and cooler as time goes on. Once again technology in order to expand however, is having to resort to multi-CPU/multi-GPU platforms until a solution can be found. At some point we'll once again be back to single core CPU/GPU, but as of now it's multi-CPU/GPU. So I wouldn't say the future lies with multi-CPU or multi-GPU at all. It's already starting to show again. Faster single core components are appearing.

Yes, that is true, however the other side of the coin is that 80-core CPUs have already been invented, along with 1Terehertz processors expected within the next couple of years, probably with multi cores.

However, you are right in that software will have to take a big leap to catch up.
 
Fair enough, but I should clarify for HOME use. Obviously you're not going to be seeing 80-core CPU's in a person's home computer. Servers and such have pretty much used multi-core solutions. However, for what they do they need it. When it comes to the domestic market there's really no reason for multi-CPU/multi-GPU. And as technology gets better more power will be taken from smaller units that produce less heat.

For instance SLi is nothing new, the name is from the old 3DFX Voodoo cards (which were multi-GPU). At the time it was a solution to the limitations of the technology. But again technology expanded and you saw cool running, faster single core video cards. Now we're back to the Voodoo stage...
 
I,m not so sure about that, you see if you can fit four cores on the same die (AMD phenom) you can produce a quad core cpu at the same cost as a single core, and the difference from 1 core to 2 is enourmous, while going from 2 to 4 wasn't that noticable.

There are quite a few games that support multi core cpu's so i think that has come to stay.

multi Gpu on the other hand will probably if not go away, be reserved for those high-end geeks (like me) and those that just HAS to have the fastest system available.
