Demul 0.582 and ArcadeVGA 5000
« on: February 12, 2014, 09:19:31 pm »
I am getting major slowdown with Demul 0.582. I am running it on a 3.4Ghz I3 and ArcadeVGA 5000 and the CPU is only at about 50% yet I am getting major slowdown. i.e. 15fps on Naomi 1 games! Running the same games on another PC with a 3Ghz C2D and HD6670 and it's running full speed no problem. So I am guessing it got something to do with the ArcadeVGA 5000 which is based on a HD5450 chipset. I am running Street Fighter 4 and PCSX 2 (i.e. Tekken 5 and Virtua Fighter 4) with absolutely no slow down on this PC, so can't understand why Demul is so slow!

Any Idea's?

demul is completely dependent on your videocard. you need a strong dx11 card if you want play anything perfectly.

I figured it was GPU limited, but 50% speed for Naomi  1 games on a HD5450  that can run SFIV and PCSX2 no problem?

As I've learned recently Demul is a lot more GPU intensive than Type X2...

remember Type X2 runs natively... Demul is emulated which generally requires 3X the processing power of the original hardware. and that's before you do any fancy upgrades like improved textures and higher resolution.

I do understand that emulation requires more processing power , but if a HD5450 based direct x 11 graphics card really is the bottleneck then Demul does seem to be over the top in terms or hardware requirements. I am running some of the more demanding PS2 games using PCSX 2 (i.e. Tekken 5 and Virtua Fighter 4) at full speed with no drop in frame rate. I have Nulldc running loads of Dreamcast games and it manages to run full speed on a much lower a spec system. I only really want to use Demul for the Atomiswave games and a few Naomi 1 games that Nulldc  doesn't run. Unfortunately I don't have the option of changing the graphics card in this machine as I am using a 15Khz arcade monitor and the ArcadeVGA is the only option that works with Windows 7. The ArcadeVGA 5000 is the latest version of the card from Ultimarc.

Just tried Demul 0.57 and it runs full speed with the Direct X 9 plug in, but some games have glitches fixed 0.58. My graphics card is a Direct X 11 card, so why is the Direct X 11 plugin so slow.

Hello,
I'm really sorry to up this old topic but I exactly have the same problem than Andypc, I got a strong PC configuration (3ghz, 16go ram, arcadevga hd5450 1go, windows 7 64bits...) but Demul is slow. No problem with Taito 2, PSX, Dreamcast... The only way I found is disable auto sort but games bugs a lot...  :/
Have you resolve your problem?
Thank you for your answer and sorry for my poor english!

What are you running for a CPU? in general emulation doesn't need a hefty Graphics processor so much as it needs a substantial CPU. As long as the GPU is adequate and compatible you should be fine. but the bulk of the emulation happens on the CPU.

i3 3.2GHz I would consider to be the minimum capable CPU I can play most naomi games with this but not Naomi 2, this even chokes on some Model 3 stuff. This CPU is barely able to run most PCSX2 games.

i5 3.4GHz or higher is recommended.

I have a low end laptop i3 that can't run Demul at all... similarly my Core 2 Quad, even with a really high end graphics card has trouble with Demul as well.
