I've tried both JP's and VPW's emulations of Rollercoaster Tycoon. No matter what, I get massive slowdown. To my knowledge, I don't have this problem on any of my other tables. Surprisingly, the JP table has slowdown (FPS in the 30s) throughout the game, while the VPW table only slows down when there's a lot of action on field (like lights flashing). Any ideas? I usually run a smooth 60fps with my i5 9700k and 1660ti graphics card on a 4k monitor.

What vpx version are you using

[onedevotee75]

Make always sure to use the vpx version the table was made with and make sure to deactivate all open background tasks, especially antivirus.

Additionally dont use any beta versions of vpx/vpinmame. Only use the "released" one.

The VPW Table is a table for 10.8. x64. Use RC 5.

 

Have running over 400 Tables on my system, all running perfectly.

Hi 

 

I had a similar problem like you in some tables.

After spent a long time to looking any configuration issue and nothing I could find

So I was looking for something in the hardware.

Take a look with Windows Task Manager in Performance View always on TOP on Backglass screen what happen with GPU memory and the same time with CPU frequency.

In my case I had a problem with CPU cooler that was not enough to keep the CPU temperature.

If the CPU temperature increase the CPU frequency goes down and GPU memory used too and the FPS goes down and performance too.

It´s a kind of Bottleneck.

I changed the CPU cooler for one new and the FPS now is fine.

I'm using VPX 10.8.0 for 64-bit. Beta 6t63503, the most recent one I could get a few days ago.

 

It is a beta, yes. But not only am I not finding problems with other tables, I've always had this problem with Rollercoaster Tycoon. Had it with VPX 10.7.

Thanks, Emanoel, but I don't think that's my issue. It's a problem with Rollercoaster Tycoon, even if I just turned on the computer. It doesn't get worse as the computer keeps running.

My guess is that it has something to do with the DMD on the playfield. I play in VR and it takes a real FPS hit but what I do is disable freezy external dmd in F1 menu (then restart game) and just use the standard dmd, framerate then hugely increases. This fix may also work for desktop/cabinet users.

if you have all the correct version of vpx/pinmame/b2sserver/freezy/flexdmd then i would start continue troubleshooting by lowering the graphic settings.
for eg the most useless one "supersamling"  set to disable, and see how this works.
 

If it´s getting better than there are some issues with the graphics and this table on your system.
drivers are all uptodate?

 

 

[licwip]

Gravy, I tried that for my cab but disabling Freezy didn't work. Thanks, though!

 

onedevotee75, I think everything is up to date. I just updated PinballY to handle 64-bit and thought I should update everything else as well. Thanks for asking! I already have Supersampling and the other Alti-Aliasing stuff disabled. In Performance and Troubleshooting, I've got Elements Detail all the way to the left for this table. I have Max. Ambient Occlusion to Disable AO and changed Max. Reflection Made to Balls Only. 

 

It's just weird to me that the JP-built table is just as bad as the VPW-built table. VPW tables are always a grind on my cab, but other than Rollercoaster Tycoon, everything else runs well enough. Being a Pat Lawlor fan, not being able to get this one to run really stings. 

 

I should point out that it's not just FPS. The latency jumps whenever a playfield light flashes, or there's any action at all. Usually my latency is no more than 0.3ms. Here, it'll shoot up into a 20-100ms range.

Have you tried running the table with just VPX and vpinmame, without db2s or any other extra program? 

[Gravy]

Is your backglass running in exe mode?
 

Is your realtime virus checker disabled?
 

 

I do recall an error with a particular table some time ago that was related to a log file constantly being written to during gameplay and the game would slow down over time, can't recall what table that was now but I don't think it was RCT. Can anyone remember hat table that was and the log file fix?

[licwip]

JP, thanks for the suggestion but it didn't change things. Takk.

 

But a big thank you to Gravy! I was not starting the backglass as an EXE. I clicked the button and that did the trick! The Backglass Server EXE is a place of mystery to me. I still don't know how to make the lights brighter on the backglass, but that's for another day. Thank you very much!

You would need to download the b2s editor and open the backglass file then edit the lights and save

Glad the exe mode worked for you, I'm not 100% sure why, but running b2s in non exe mode is generally a performance hog. Perhaps the b2s gets a dedicated core or something in that mode rather than having to share the core with VPX at the same time? Anyone know the reason?
 

JP's suggestion of running temporarily without a backglass should have indicated if the backglass was the culprit.
