Same game slower on faster machine (only one core used)

Hello,

I am having two machines, both running Ubuntu 12.04 64-bit and Wine 1.4.

The older machine is a Core 2 Duo E6600, 4GB RAM, GeForce 7950GT.
The newer machine is a i7 3770K, 16GB RAM, using on-chip Intel HD4000 graphics. When benchmarking the two machines on native linux games, the new machine performs 2..3 times faster in terms of fps depending on the game used.

But I have the following issue when running the preview release of the upcoming Zusi 3 Trainsimulator (http://www.zusi.de/pages/dehaupt/zusi-3 ... d/demo.php)

Old Machine:
Scenery loads pretty fast - both CPU cores are working during loading and also running the simulation. With default settings the simulation yields at 5fps, with some tuning it gets up to 20fps.

New Machine:
Scenery loading is very, very slow - so far I haven't even been patient enough to wait loading to complete.

I have no clue why it is so slow, the only weird thing that I have noticed is that only one CPU core is active.

I have read the sticky thread about Ubuntu 12.04, it doesn't seem to me that anything there could be related to my problem.

I am pretty new to wine, so any advice what to check / change / try is very welcome.

Thanks
Christian

I think thats called really poor to bad Intel Linux graphics drivers vs decent nividia drivers.

Intel's Linux drivers are generally inadequate for Wine. The simplest way to improve performance would be to get an Nvidia card for the new machine.

There are a couple of wiki pages with tips for troubleshooting performance issues.

Thanks for the fast replies. It's a pity the Intel drivers don't go well with Wine (or the other way round?), since the performance of the Ivy Bridge HD4000 graphics is rather nice.

I have ordered a new Nvidia card a few days ago anyhow, so I shall wait and see.

Cheers
