Atomic Systems

Hello all,

Noticed that on purchase of the Class 444 pack from GetGames today, that I seem to be having some possible hardware problems since its install.

On completing the tutorial, I ran the first scenario - Epsom Down on Career Mode. On open the scenario, I had really bad jelly cab, scenery flickering, terrible shadow flickering. I immediately closed and reopened the scenario and it was fine no jelly cab this time but still some really bad texture flickering and shadow flickering, the windscreen of the unit was flickering extremely bad as well at certain points as well, it wasn't the usual jelly cab flickering.

Also, I noticed things seem to be a bit blurry on TS2012 since its last update.

My system specs are:



Windows 7 - 32-bit.

AMD Phenom II X4 955 Processor 3.20 Ghz QuadCore

8GB Ram (3.25 GB useable) (Running the memory switch)

ATI Radeon 6900 HD Graphics Card

Creative X-Fi Soundblaster Sound Card

In game settings SSAA 2x1, all settings highest except particle density - low. Shader Quality - Medium and Shadows - Low.

Cleared the blueprint cache after installing earlier and now Verifying the Cache.

Thanks,
Shaun

It may be worth while trying your current settings using the '30fps lock' on the railworks launcher. RSC have said that this issue is down to having the sim produce lots of frames after entering sparsely populated areas, they explained the latest patch to the sim as having 'Less GPU stalling at high frame rates', but it seems you may also need to use the built in 'frame rate limiter' on your set-up.

Currently have the FPS limiter at 60 FPS but will try 30 and see if it makes any difference.

Thanks

I often get the 'Jelly Cab' if I play one scenario after another without exiting and restarting Railworks and in some cases in free roam scenarios, after swapping loco's despite having my FPS locked at 30, I presume having more RAM may help?

Nope. It's the Core Program which is at fault. It is the same in any simulation game I have tried, but some are better at hiding the problem using a better game engine. WoS3 gives me brief 'jellycab' sometimes but it quickly dissapears whilst playing. RSC have said however that the last Core Update was an improvement to the 'jellycab' problem, it was never stated that the issue was completely fixed.


The only simulation game that I havent seen 'jellycab' on is Microsofts Flight Simulator (as the 3D environment moves around a fixed position), where as most railsim games have 'the player' move Around the 3D world.

Thanks guys, I have applied the 30 FPS limiter and still seems to be the odd windscreen flickering on the Class 444.

I haven't tried any other route yet to see if it gives the same results.

i dont use the programs own FPS Locker, i use DXtory, its free and i just set the lock to 40-60fps and everything is smooth with no flickering, there is some jelly cab but it seems to smooth it out
