Thanks for the reply,

Cars rolling over from slicks can "usually" be solved by increasing the tyre pressure to 32-34 psi (proper in real life psi for slick tyres).

With the driver-position, the easiest fix I could think of is moving the steering wheel & it's column upwards, then updating the steering animation location.

Hi, could you increase the suspenion motion-range to .250m.

The rear suspenion is easily damaged over jumps, hopefully more suspenion travel can mend that.

Also I wish the steering-wheel didnt block the dash so much; cant really see the rpm & speed dials (even with view Z-offset at -0.050m).

Thank you in advance & nice mod by the way.

Hello
I made a grip-setup for this pocket rocket of a car, my PB on Westhill International is 2:07:27; the rear is more stable under heavy braking & it’s "more difficult" to rollover now, give it a test if you want.

I haven’t done much drag-racing, so I don’t have a setup for that yet.

Here’s a suggestion though, do you think you could change the driving-position into a central single-seater like the McLaren F1?

I think this will suit the drag-spec theme of the car + it will help improve the weight balance.

Nice work with the mod.

Rockingham ISSC - FXO SuperTourer; 2022 Feb 17.

A good breakdown on fair overtaking & defensive racing-techniques.

Yep the screenshots load much faster now, since it’s no longer 5MB per image

Doing the Trails is like learning the Nurburgring for the first time but with some stunt & jump driving elements mixed in.

Best to have some music running in the background & just take your time; read the signs, if confused don’t drive ahead blindly or you’ll risk getting sent back to spectator-mode.

If your car is stuck or badly damaged, use the command !tow
There are also pit-stops along the way.

Making it to the end is an achievement itself; if you can remember the course, you could attempt to time-attack it like a rally-stage.
The thing I find most difficult are the jumps, you’ve the get the speed just right; or risk suspension damage.

The layouts are challenging yet fair & entertaining, nicely done P V L.

i say you don't see this lag when you use 50 Hz and fps because the LFS Physics engine calculating 100 fps. 100/60=1,666666. 100/50=2. Thats the reason why it run smoother with 50 fps. Also other persons on the forum said this already, i am not the only one.

Thanks for the explanation, I wasn’t aware of that.

So which operating system are you planning to use with Ryzen with? Windows XP, 7, 8, 10 or Vista ?

At the moment Ryzen motherboard driver’s only support Windows 7, 8.1 & 10.

Microsoft being a falota, has blocked Window Updates on Win 7 & 8.1 machines running the latest CPU; in an effort to force people to switch to Windows 10.

Running Windows 7 & 8.1 is not a problem; there are multiple guides online to unblock windows update & on how to install windows onto the newer CPU systems.

But Windows XP is going to be a problem, I can’t find any guides online; it is “technical” possible to run XP on Ryzen but even if it runs you most likely won’t get the maximum performance from it since there aren’t any drivers that support XP.


I can only think of 2 options:

1. Use Windows 7, 8.1, 10 on Ryzen > install a virtualization software like VirtualBox or VMware (both are free for personal use) > Install windows XP in the virtualization > run your games there.

2. There must be ways to make games from the XP era to run on modern OS. Maybe through unofficial community patches, No-CD exe, editing file settings, using compatibility mode.


What games and software do you have that only runs on XP? Or are you going to just use Windows 10 with Ryzen?

I’m confused by your reply; Vsync locks your FPS to your monitor’s refresh rate; e.g. 60Hz monitor = 60 fps when Vsync is on.

My monitor currently runs at 60Hz so why are you suggesting me to force it to 50Hz? A miss-understanding I guess. Unsure about overclock my refresh-rate since monitors don’t have fans & rely on passive cooling, they don’t have the ability to deal with the extra heat.


a. Do you usually build your own PC, by buy individual parts? Or buy pre-build PC systems?


I’m in a similar situation looking to upgrade my aging desktop PC; at the moment I’m waiting for Ryzen 2 or Ryzen 2+ which will be 7nm & free from the Spectre security vulnerability, coming out at 2019 maybe if things go to plan at AMD.

Hopefully by that time, DDR4 memory prices will be closer to normal.
https://en.wikipedia.org/wiki/Zen_2


You’re in a tricky situation, you can either:
1. Learn to overclock your AM2 CPU.
2. Replace the AM3 motherboard.
3. Get a pre-owned Intel i5 CPU & motherboard that supports the DDR3 that you currently have.
4. Pay double or triple the price for new DDR4 RAM, a new motherboard & get a new CPU that is vulnerable to meltdown & spectre.
5. Wait for AMD Ryzen 2 in 2019+

b. What games do you play or want to in the future? list the ones with the higher system requirements.

FYI - The higher the RAM speed the higher the FPS. Ryzen & APU in general is very RAM speed sensitive.

Are you going to use this as your main PC gaming platform?

Quote from matze54564 :

0,04 or 0,04 s delay and without buffered frames maybe 0,01 s delay are absolutely irrelevant. For 100 fps you should have a 100 Hz Monitor, all other configurations are not 100% optimal.

Going slightly off-topic but have you ever tried playing LFS without using Vsync?

With Vsync @ 60fps my steering inputs feel very sluggish, making counter-steering more difficult.
Things might be different on a 144 Hz monitor, or through AMD Free-Sync or NVidia G-sync.

If you cap your FPS at your monitor's refresh rate, a drop of one or two frames will cause noticeable stutter. What’s why you add +20 to +40 fps to your refresh rate; this way, you will have some 20-40 buffer frames per second that can make up for potential frame loss.

1. Have you tried running HD 6870 or RX 550 on the AM3 motherboard, “without” the PCIe USB 3.0 Controller connected?

Other than that & resetting your BIOS settings, it looks like your AM3 PCIe x16 slot could be faulty.

2. You don’t need to use Vsync if you’re not getting any screen tearing like this, just limit your fps to 100; also using Vsync creates input lag.



For better FPS try the following options in LFS.
1. Graphics > Car and helmet Skins > compressed & Dynamic reflections on cars = 0 or 1
2. Misc > Multiplayer speedup option > Yes > choose a distance you want distant cars to not be drawn. (this option can sometimes create stutter)
3. Dynamic LOD reduction = 1.0

1. Does CPU-Z show HD 6870 connected at 4x PCIe, on both your AM2 & AM3 motherboards?

2. Do you have a spare GPU to test, to see if your AM2 & AM3 motherboards can function at 16x PCIe?

1. Have you tried testing without using “ramdrive” & just use virtual memory set at 4GB to 8GB?

2. Have you checked your HDD SATA or IDE cables; a slightly broken SATA cable can really slow your system down.

https://www.reddit.com/r/buildapc/comments/3f5y41/inexplicable_slow_performance_check_your_sata/

Hardware wise your Athlon II x4 640 & HD 6870 is certainly powerful enough for LFS; I’m on a Core 2 duo @3.2Ghz_3GB-DDR2 RAM_HD7850 & I get 215fps in blackwood @ 1920x1080 60hz resolution; on an empty starting grid, in-car view.

If it was a faulty hardware (CPU, GPU, motherboard, RAM) I think you would be getting system crashes or blue screen of death.

Therefore I believe your slowdown is from BIOS settings, drivers, software or thermal throttling.

What fps are you getting in LFS & what screen resolution are you playing at?
Trying to work out if youre CPU or GPU bound.

It seems like a terrible time buying new or pre-owned PC hardware at the moment.


Hardware –
AMD CPU’s is only affected by spectre; Intel CPU’s is affected by both meltdown & spectre.

Intel & AMD is currently facing lawsuits. As of now June 2018 there is no CPU on the market that is immune to both meltdown & spectre without some performance penalties.

I have a feeling that in the next few years, there will be a lot of companies upgrading their PC’s, to get away from the vulnerable & slowed CPU’s, which could mean there will be a lot of second-hand computer parts on the market.

DRAM is currently 3 times their normal price at the moment; Samsung, Micron & Hynix is getting sued for “fixing prices”.

GPU is expensive at the moment because of crypto-currency mining & from the high DRAM cost, but the price has fallen back a little since the crypto market has crash.

CPU AMD – Avoid the older AMD CPU’s; they have very poor single core performance which is important for gaming. The current “2017 Ryzen” line-up is very good though, but you will need new “DDR4 memory”, which costs as much as a new CPU at the moment.

CPU Intel – Core i5 (mainstream) or Core i7 (performance) line-up, Quad-Core from the “Sandy Bridge” generation or newer, make sure the CPU runs on the DDR3 RAM that you currently have.

Sandy Bridge (32nm) - 2011
Ivy Bridge (22nm) - 2012
Haswell (22nm) - 2013
Broadwell (only support “low voltage” DDR3 so avoid this CPU generation)
Skylake (only support “low voltage” DDR3 so avoid this CPU generation)
Kaby Lake (only support “low voltage” DDR3 so avoid this CPU generation)

i5 -

i7 –
https://en.wikipedia.org/wiki/List_of_Intel_Core_i7_microprocessors


Motherboard – Something that has “solid capacitors”

AS Rock, Asus are good motherboard brands, Gigabyte great in the past not sure about now, avoid MSI; from what I’ve read.

Make sure the motherboard has the same “socket” as the CPU that you’re buying.

If you have a decent Power Supply Unit & case cooling, maybe you should try overlocking your current CPU? remember its the high voltage and temperature that kills, not the clock rate.

Are you having this “slowdown” only recently, was the performance fine the year before?

If so I believe the slowdown is caused by the “Meltdown & Spectre vulnerability” updates from Microsoft, which can slow your system down by 5% to 30%.

There are ways to disable the meltdown & spectre protection so you can get your performance back.

But I don’t recommend you doing that if you’re using your PC for “online banking” or anything that is data sensitive.

To disable Meltdown / Spectre Protection, download InSpectre

https://www.grc.com/inspectre.htm

Download it > right click on it > run as administrator > Click on Disable Meltdown/Spectre Protection Button > Exit > Reboot the PC > run InSpectre again > check to see if Both “System is Meltdown/Spectre protected: NO”

Info about Meltdown and Spectre -
https://www.reddit.com/r/OutOfTheLoop/comments/7p7vzi/can_someone_explain_what_are_the_meltdown_and/

A tarmac rally style circuit through the side roads of Westhill, comes with 40 starting grid.

Not recommending anything faster than a UF GTR or a Formula XR.

Update v1
- Reworked 2 corners in sector 1
- Moved the barriers under the starting lights to expose the grass so “dirt drop” can be used to extend your drift as you exit
- Tidied up the layout in general, barriers are now smoother(no tiny gaps)
- Made the layout less confusing by adding a few signs, banners & armco etc



I made the layout open in mind. Shortcut entrances are marked with yellow lines, they allow for safer overtaking. There are also a few alternative routes that you can take.
Because of its open nature you’ll have to be wary at certain parts of the track since paths will merge together.

Sector 1 – Based on Ebisu Minami


Sector 2 – Infield of Irwindale Speedway


Sector 3 – Twisty Mountain Pass, copied from an unknown layout (Hopefully you won’t mind me using parts of your layout)


Sector 4 – Copied & simplified from an unknown layout as well, it feels like the outer section of Irwindale
